You just have to do a meta analysis on the implied values of various martial traditions and when and how they became LARPing.
Without scholastic wrestling wrestling in the united stated would have evolved completely into LARPing ala professional wrestling such as the WWE.
Sometimes they don't transition into larping but evolve into a dance style when their is a ban placed on the practice of Martial traditions. Examples of that would be Cossak dancing, capoeira, and the shaolin styles of kung fu.
Notice how allowing the cossak military tradition to become a dance allowed it to be appropriated by the dominant Russian culture and exported giving the dominated culture a means of identity in their subjugation.
What happened in the case of Wing Chun is people looked to create a functional martial style from shaolin kung fu but enstead created a LARPing style of TMA. Something similar to this has been done with a TMA developed out of cossak dancing recently called Hoppak.
Nottice at how innefective it is to try to recreate a functional martial art out of one that has become a dance such as the case of Hoppak.
Can you imagine how innefective it would have been if pre world war 1 the cossaks rebelled using Hoppak as their melee system?
Considering this it then makes sense why a conquering culture would allow the dominated culture to maintain Cossak dance or Shaolin style fung fu because it is incredibly effective at undermining the dominated cultures Martial Traditions from within.
Now here look how effective Cossak dance is when used as a source of crosstraining with a base in a living effective martial tradition such as boxing.
Vasyl Lomechenko stopped boxing completely for four years and trained Cossak Dance.
So it creates a strong movement base to train real fighters from in service of the dominant culture as well when done properly.
