More specifically, for libraries, we should only ever use replacements
that are ABI-compatible.  (That usually means that the major and minor
version numbers are the same, which may be what Andreas had in mind.)
Anything else is most likely broken.

For command-line tools, I think we should only graft with replacements
that are backward-compatible at the CLI level.  That requires manual
review of the changes, I guess.

Thanks,
Ludo’.
