The developers of the Alpine Linux-based postmarketOS mobile distribution today that they’re now supporting the systemd init system alongside OpenRC and other alternative init systems.
and:
postmarketOS currently supports the Sxmo, Phosh, GNOME Shell on Mobile, and KDE Plasma Mobile UIs. While the Sxmo images will stay with OpenRC, the GNOME and KDE Plasma Mobile images will be built on top of systemd
GNOME and KDE images will be built with systemd by default. while using systemd will be optional, polyfills - a somewhat messy way of providing systemd features with other init systems - are the only way to support GNOME and KDE and will eventually become unmaintained by PostmarketOS.
to clarify:
and:
Does that mean those images are not built on Alpine Linux, or did they somehow kludge glibc into it just to build systemd?

not too sure how systemd was implemented, but it looks like systemd is just built with musl libc as systemd is mostly compatible with it.
