I guess with the changes that showed different thing like fastpath,
that makes sense. But if we just mapped the states that are there
today straight off, is there any case where waiting can be true, when
we're either idle or idle in transaction? I think not..

Yeha, that seems inconsistent. Using a single character might work -
but it's not particularly user-friendly to do that in the view itself.
