I have opposer your solutions because I think they are bad solutions and
I can see a better one. I have proposed to help design said better
solution, you have always declined but never given technical arguments.

No, you have many times refused to allow them being solved.

Then install pkg-config in a local directory. If you can compile
ffmpeg, then you can install pkg-config.

Their needs are relevant. Their ill-advised solutions to meet them are
not.

This is not true. I have already proposed many times to help you find a
*good* solution to your pkg-config troubles.

Sorry if this was really not clear:
I do not have installation rights on every system where I
(at least from time to time) test FFmpeg.

My primary point is though that I consider it completely unacceptable
to constantly send messages to users that their needs are completely
irrelevant to us.
(I already realized that nobody is interested in me testing FFmpeg
and I should probably be happy about it.)

Just out of interest, which systems are these? OS/2? While this
question could be interpreted as facetious, let me say I am wholly
just genuinely interested in such systems - where modern FFmpeg can
still build or operate.

Also for the record, some distros (including Fedora) have actually
stopped using original pkg-config since a few versions ago, instead
opting for a new re-implementation called pkgconf
(https://github.com/pkgconf/pkgconf).

Best regards,
Jan

I doubt there are systems where ffmpeg can be installed but not
pkg-config.

But if you really think there are, the best solution is to provide a
minimalistic emulation of pkg-config. I would not object if you propose
a patch adding such a script in tools, and I would even offer to help,
to the limit of my ability. This would have the benefit of only
impacting people who want it, not slowing everybody who runs configure.
