Yeah, unfortunately sfdisk was rewritten upstream, causing several
problems:

https://bugzilla.redhat.com/show_bug.cgi?id=1183236
https://bugzilla.redhat.com/show_bug.cgi?id=1212507

Ideally I'd like to remove our dependency on sfdisk, but it's rather a
lot of work.

I think a compile-time check would just cause the API to fail in a
different way, so I don't think it would help users very much, unless
I'm misunderstanding what you mean.
