I know this reply is untimely but it might be useful anyway for other people wanting to strip systemd where it theoretically would not be needed.
Even for your text only wsl1 where it systemd is not even used, it cannot be removed without hindering redhat package manager.
You need to put back into your system at least :
/usr/lib64/rpm-plugins/systemd_inhibit.so
/usr/lib64/libsystemd*
/usr/lib64/systemd/libsystemd-*
else rpm won't be able to install/update anything in turn messing up yum/dnf.
The above libs are not a direct requirement of rpm, they are probably needed by something used during the package management process, none the less without them you cant install/upgrade anything.
