Maybe Gary and/or Wade can give the opinion of the Activity Team on this?

Would be good to have some way of tracking what needs to be solved
before we can do the switch. Two questions off the top of my head are
how first-time activity authors are going to package their software
and also what those people will have to do to modify an activity
installed in their system. (But maybe not discuss these in this
thread?).
