Instead of making the visibility of this section in user profiles
dependent on the model, its now checking if you can check mutual rooms
and using a busy indicator. There's also a label for when you have no
rooms in common, which is a rare case (for example, banned or left
users.)
Our previous iteration is hitting some limitations as the power of
profiles on Matrix grows. For example, where do we put common rooms or
extra profile fields?
I re-arranged everything to group similar actions together - instead of
throwing it all into one big list. We basically trade vertical for
horizontal space, and gives us more headroom for extra fields when we
want to add more.
