That's a good point.

If we are going to stick to ASDF 2 indefinitely, would it be a problem
to move to an xx.yy.zz format of versioning, where delta(yy) = change in
API and delta(zz) = patch?

The reason I suggest this is that it might be easier to keep track of
the way in which the xx's correspond to features you need that way.
Most people who are worried about whether their ASDF system definitions
will work could safely ignore the zz's.

Personally, I have pretty much lost track of when features I need were
added to ASDF.

Just a thought....  If it's too much trouble, don't worry about it.
