Not sure. I did come up with a better solution for the ABI bump
problem, though, and wanted to run it by you.

So rather than just guessing based on things like major version of a
library whether dependents need to be bumped, I would suggest we add
an "abiversion" keyword. Changing it in any way would imply that ports
depending on that port would be rebuilt.

This would imply that there would be a need to be able to query what
"abiversion" is currently installed.

I think hashing out how this might work in a bit of detail will
reveal whether it is too much work to bother with or relatively easy
to do. (My guess is probably the former, but it would be nice to
figure out what is involved first.)
