That's true, there's lots of information spread all over the place, that
is either too detailed/deep, or too vague.

For example there is also:


In any case, barring better documentation or guides, using example
implementations simpler than glibc might be useful to people. So I
offer libbsd, but I'm sure there are many others. We could perhaps
even create a wiki page listing some of those pointers.

libbsd for example exposes setproctitle() with different versions.

You just switch it, code compiled against the new version will require
at least the version switching to versioned symbols, code compiled
against an older version will keep working with both.
