I agree this change sucked and showed us we have some real issues. I
will point out that if we had been using the basichash signature
generator, it would likely have picked up this change and rebuild all
the appropriate pieces.

This illustrates why we do really need to switch to the basichash
dependency model even if some things are going to rebuild a bit more
often as humans make bad judges of what needs rebuilding...

Cheers,
