I intend to orphan the hercules package. It's an s390(x) emulator and
the package itself is in fairly good shape overall. It's mostly that I
have no use for it for several years now. (And mostly I do not want to
feel responsible for it anymore.)

Upstream has been trying for years to get a 4.0 release together[0], but
the last commit for that was back in 2019. The website also moved around
a bunch of times. So it's unclear at this point how maintained it is, if
at all.

qemu also offers a usable s390x emulator. I'd say that hercules is a lot
more true to the original hardware, especially if you need to emulate
the platform for something else than Linux. Or if you want to emulate an
ancient System/360 or System/370.

The package's description is:
