I just found this example about building "true connection" in bachata (subtitles in the video explain perfectly what they mean at each stage): slowing down, ignore the rhythm for a while but get into a contact impro.
It even shows exactly what my WCS instructor meant: the guy gets down on his knees and starts touching first her legs, than hips and above (let's ignore the kiss for now). That's why we did the massage in the workshop. One problem with that is: when I do this with an unknown follower she will think I'm creepy or weird for sure. All this doesn't work on the social floor. The other question is if this whole philosophy makes sense. It's not new: I remember already 10 years ago I was in a Forro workshop with the same content (knee down and touch each others ankles first). I left the room after five minutes. I don't say it's complete nonsense, but it's contact impro, not partner dance, and it doesn't fit well to latin dances.
I have several opinion on this type of advocacy on interaction between two people (to music as a back drop). I didn’t say concept. It is more promotion and evangelization of this idea which is not new.
You rightly sighted contact improv which has been doing this type of stuff for a long time. I have seen instructors from regular partner dancing also try to bring some of it into which ever dance they are teaching. That too is not new and has happening for a long time.
First thing that comes to my mind is that this feels like using dances as an excuse to pseudo make out with a person. It is one step short of making out The music doesn’t matter and is in the background as some kind of mood enhancer.
Second is it can be justifed for any type of dance where more than one person is involved. Irrespective of the partner dance structure and irrespective of the music, you can always find ways to incorporate that into teaching. Except perhaps ballroom because that is very rigidly codified.
Third, this type of idea of connection is a very different one that what we normally seek through partner dancing. It is like forcing chemistry and connection on everyone and everywhere. The whole goal is to forcefeed the connection and that too a very physical one.
Fourth, if you notice it is always accompanied by slow tempo music of a certain feel. I won’t call it romantic music. Music has certain feel on sensuousness or tries to evoke that feeling in the listener. They won’t demonstrate it to music that doesn’t fit that.
Fifth, if this is the connection and you can create it with a stranger, go to the night clubs. You will see a lot of grinding and similar stuff going on a nightclub dance floor. They do it will all kinds of movements to all type of music. Fast, slow, hard hitting, doesn’t matter. At least they (people dancing in the night clubs) are explicit about it, will match rhythm to the tempo of the song. That’s a dancing equivalent of one night stand with a stranger. Almost like having vertical sex with a stranger with clothes on.
Sixth, teaching this to average or beginner dancer can lead to a disaster on the regular partner dancing dance floor. Fluidity of physical movement and body movement is a skill. How you see the women dance in that instagram example video is not easy. Some men are just clumsy and lack fluidity. Most of the beginners are in that category. If they try to dance with a lady dancing like that they will come across as a creeps.
Seventh, it can give a wrong idea to people on what is permissible on the dance floor. This I think is the biggest risk. We already hear complaints about awkward behavior without having to add on top of that. Instead of dance being universal (anyone dancing with anyone irrespective of age, shape, or size), this will narrow the participation. Not everyone will feel comfortable dancing with everyone. You might feel comfortable with only a handful of people.
If a couple wants to dance in risqué they don’t need a class or workshop
I would label this as promoting junk connection. Or connectivity p*rn
