The interesting question now is: what qualifies an 'important fix' ?
IMHO, when the current stable release is really broken.
But: in this case, most likely, the distros will clean up the mess anyways,
so again we can relax and let the distros do their job.

Exactly. I'd suggest doing development/testing on stable releases
of various major distros (whichever individuals prefer).

That's the important question!

I would prefer dropping that completely from the main codebase, and
instead build an separate meta-build layer. Essentially just a shell
script that fetches the libs, builds and installs them to some suiteable
prefix in the correct order and the builds LO. It would override the
standard search pathes (mainly pkg-config tweaking). That script would
take the same layer as the distro toolchain in the whole stack.

I would prefer when it *only* takes a bundled library, if I explicitly
force it to do so for some damn good reason.
