And I'm not worried about that, because I believe that app developers 
who think that they can deliver adequate performance under these 
conditions will either not constrain, or use optional constraints.

Rephrasing slightly (there was a dangling "not" there): I'm afraid that 
application developers will be unable to avoid selecting devices that 
give a bad user experience.

App vendors (with Dan being one of the vocal ones, I think, but he can 
speak for himself) have said that they want to be able to tell the user 
"you need to do X to use this application/mode/function" instead of 
fielding the support call that says "why does this app look so bad when 
I don't do X".

Yes, with the dangling "not" edited.
I don't think we've changed opinions much recently.
