That sounds reasonable to me, obviously we'd have to look at how
exactly the annotation ends up getting done and general bikeshed colour
discussions.  I'm not sure if we want a specific "safe for unwinder
section" or to split things up into sections per reason things are safe
for the unwinder (kind of like what you were proposing for flagging
things as a problem), that might end up being useful for other things at
some point.
