Potential API changes for mop?

Question for Blizzard:

Planning to do any changes or add something new (potentially) for API? Planning working on something and could be good information to know before hand.

Cheers!

Current MOp beta build API option supports DIrectX 11 and 12 and has RTX low, mid, high shadow effect and reflect not sure if it has any other classic era changes too like at the moment only panderian character has full hd and moving facial features while Worgen and Goblins has HD update and only partial facial effects like jawbone and eye blinks minor update eyes update from vanilla so far other races are stil same . Auction
house MOP has minor changes too index system for amount of same items other sells are now linked together but you still need place a prize in manual AH menu visual seem to be a same I guess massive API visuals changes was in WOD expansion when all playable models has full hd update and faces not just pandas

I tend to believe the OP question was about the addons’ Lua API, not graphical stuff.
