We (Chrome) would like to ship this feature in the nearish future but I'd like to make sure we have consensus that this is a good idea and the current state of the proposal is acceptable before we do so. The WICG repo has been pretty quiet so I'm hoping to get more engagement here.

Hi,

Sorry for the slow answer.

I think this is an interesting proposal. As you say, the lack of specification and interoperability when it comes to which viewport related APIs relate to which viewport is bad, and clearing this up is something we should do.

One thing I am not entirely sure is your claim that once the new visual viewport API will have been out for a while, it will then be safe to switch the old ones to the layout viewport. If this caused breakage now, why would it not cause breakage in the future? Maybe new sites will pick up on the new API, but that won't fix the old ones. What am I missing?
