I don't think it's a good idea to guard things like this on SOURCE_DATE_EPOCH. This variable was only meant as a compromise solution, and we should be pushing projects to avoid using it, and slowly "come off" using it, not to make more reproducibility features depend on it.

For example GNU projects are supposed to have ChangeLogs, eventually the build system chould be reading the date from the ChangeLog and setting SOURCE_DATE_EPOCH itself, without needing a high-level distribution package builder to do it.

I'll see if I can say something more specific to hostnames on the ticket.
