I see Jürgen replied "yes" to this, but I'm not sure about 1.
above: I think it's quite reasonable to expect that paths without
condition may gain a condition. Just like paths now having a
condition and (perhaps temporarily) losing it shouldn't all of
the sudden become "always available" when they weren't meant to
be.

As far a 3. goes, I'm also unsure in how far this is any better
stability wise (from a consumer pov) than allowing paths to
entirely disappear.
