Yeah, my answer to that is still "why is this particular case more
important than any other ABI breakage you might cause while hacking
on a back branch?". I quite agree that being able to check for ABI
breakage locally can be useful. But what we ought to do is make it
easier for people to use libabigail for that without spinning up a
local buildfarm instance. Perhaps we could extract the buildfarm's
ABICompCheck.pm script into some standalone tool.
