I think a hard dependency like this is too much.

I would very much prefer to deal with it similar to how we deal with
Guile-Newt or Guile-Charting: a soft dependency that’s entirely
optional.

But I guess that also depends on what Guile-Semver is used for.
I just posted a question on this topic in that thread.  :-)

Thanks for reviving this patch series!

Ludo’.
