Yes, it simplifies the code. Here are the two patches for HelloMesh that
do it:

Yes, but without holding other things back in between Release Candidates.

Irrespective of #6299, activities which are shared and lose their

otherwise will probably appear to continue to function. There's no UI
indication of failure. The bug for this is #5620.
