I’ve been bitten by this once because I don’t run ancient CURRENT/STABLE (r279198) and here are a couple follow up commits bumping tools versions in the past (e.g. r278975, r269662, etc).

It’s a terrible thought. We’ve done the bootstrapping thing for 15 years with very few
bumps and biting. No need to ditch it because lately we’ve been updating yacc
more often w/o bumping the revision.

Don’t remove it. There was more blood on the floor before we had it than after. It
documents how far back in time we try to support. Sure, things get missed, but
it isn’t always clear why we have things in the bootstrap tools. Having them
documented this way makes it clear.
