That said, I think they are problematic too, in that I don't think
they are universally available, so if you want to trace some
executable without build ids - and there are good reasons to do that -
you might hate being limited that way.

Right, but these days gdb (and other traditional tools) supports it and
downloads it (perf should do it with a one-time sticky question too,
does it already in some cases, unconditionally, that should be fixed as
well), most distros have it:

So I'm literally thinking one very valid case is debugging some
third-party binary with tracing.

End result: the whole "most distros have it" is just not relevant to
that situation.
