We do have enough RT signals, as the patch attached to [1] demonstrates.
I haven't tried that patch with recent versions of systemd, though.
Unless systemd has started using even more signals or introduced even
more gaps for no reason at all.

That's Debian unstable and Gentoo /stable/ thank you very much. :)

Gentoo dropped support for GNOME and KDE years ago (except for some of
the base libraries such as glib and gtk+ of course). The point being
that these fat window managers run utterly slow (exactly as they do on
much more recent x86 hardware).
Interest in supporting systemd therefore never went beyond the
purely academic interest displayed in [1]. Luckily, Gentoo already uses
an alternative, modern init system. Gentoo/HPPA has little need for
systemd, I would guess.

Sounds like a lot of work.

Gentoo has no need for systemd so all these changes would mean
upgrading kernel and libc requires a lot more attention, and systemd
could equally well compact the ill-chosen RT signal range.
