For me, the reasons for getting rid of elogind were dmesg errors like these (only with kernels later than 5.4, and regardless of kernel config, kernel commandline or BIOS settings):

Turns out it didn't stop the freezes, but here's my experience with seatd FWIW.
seatd, dbus and polkit just need libelogind to run (elogind is only a buildtime dependency; the headers could be packaged with libelogind, or separately (an "elogind-headers" package would be nice, see below). I tested libelogind-249-pre, though the binary package also works. I've already been using custom-built dbus (no audit) and polkit (with duktape, which fortunately is the default now). For suspend, shutdown and reboot I added the following to /etc/sudoers:
%users ALL = NOPASSWD: /usr/local/lib/suspend,/usr/bin/openrc-shutdown -H 0,/usr/bin/openrc-shutdown -r 0
suspend is a little C program (doesn't currently work with linux-next, suspends only once, then hangs; works with mainline and 5.4):
#include <stdio.h>
#include <stdlib.h>
int main(void) {
FILE *state;
state = fopen("/sys/power/state", "r+");
if (state == NULL) {
exit(EXIT_FAILURE);
}
fprintf(state, "%s", "mem");
fclose(state);
exit(EXIT_SUCCESS);
}
I put it in /usr/local/lib because I don't want it on my path. This program could of course be expanded to handle shutdown and reboot as well (not currently needed). Who needs loginctl? For XDG_RUNTIME_DIR, I tested adding
export XDG_RUNTIME_DIR=`mktemp -d /tmp/xdg-${UID}-XXXXXXXXXX`
echo "XDG_RUNTIME_DIR=${XDG_RUNTIME_DIR}" > ~/.pam_environment
to .bash_profile, which works perfectly well. There is also a pam_rundir package, which I also tested (it creates the usual /run/user/$UID).
The elogind-git package needed a hack to build (here's a working PKGBUILD):

I tested {,lib}elogind-249-pre built with this PKGBUILD, see below.
Does seatd actually do anything on a system with a single logged-in user? "ps axo seat" came up empty except for a column of dashes. (Even when I logged in again on a different tty, which incidentally took very long, and I didn't get graphics - it turned out to be a libelogind-249-pre issue, works with {,lib}elogind-246-10, including the one built against elogind-headers. Maybe polkit and dbus also need to be rebuilt, but since seatd doesn't do anything for me, I'm done testing).
