Ah! Now we're getting right on the spot, where it hurts, and we're
finding the root cause. That's a very good thing. Let's dig ! :)

Solution: if given a reasonable time for project B, ignore project B,
declare it bad, and point fingers at the contributors of project B for
not doing the needed maintenance work.
But by the way, what is that bad library X that you're talking about,
which is constantly breaking backward compatibility? Isn't *that* the
source of the issues to begin with? Shouldn't we then just avoid library
X and find a better replacement, which does *not* break the API every

They are wrong. They *must* upgrade, because upstream for library X will
anyway supporting the old deprecated version next week.
That's a simple easy rule: the very latest version of *any* component
should always be the winner. Everyone should adapt.
Oh... and did I mention backward compatibility? Yes I did, and yet
everyone understand why the Linux kernel never breaks userland... :)

Which is due to bad upstream breaking compat.

... as ways to avoid issues due to bad code. Let's fix the code, or
avoid the bad one.
