They will change it, since the current caps is for 6GB devices, but there is very little chance that they will move it above 7GB, so the 16GB devices will only serve for less reloads, not for apps. We'll know soon but that's what they have done so far whenever there were 2 different RAM version of the same chip. Again I wouldn't speculate too much on why then 16GB, since it was already part of the M1 and can also incentivize higher storage tiers... (just like 6GB in 2018)I personally could not recommend the 16 gig model to anyone if they didn't need 1tb+ of storage right now because of the cap on ram usage per app. If they change that it'd be a different story.
