I think as time goes on modernized form and traditional form/fighting will move further and further away from each other.

We already are, within our communities, developing an easily seen seperation between traditional and modern sets.
If people stop using them to teach fighting ( leave that to drills, equipment work and sparring) and stick to suing them for other purposes, forms will find their place.
Its when people become disilusioned with the results that things get dropped,
Doing forms and being told you are learning to fight and then getting your butt kicked because real fighting is nothing like forms is not the way to go.
