This is strange, because the systemd prerm won't let you remove it if 
it's the running init:

https://salsa.debian.org/systemd-team/systemd/-/blob/debian/master/debian/systemd.prerm

In general, you're better off switching init during the installation:

...if you want to switch away from systemd on a running system, it's 
doable, but needs some care:

HTH,
