I thought that information came out several times in the thread you mention
having started -- that it was possible to install the base system, then
disable and remove the main systemd component, just leaving some
of the pieces that have been picked up as dependencies by other
packages.
Maybe the discussion of using more advanced techniques to keep from
ever installing systemd in the first place hid the information about the
removal approach.
If so, it would seem to be worthwhile to have this separate thread, as well.

Thanks for the report.

One of these days I'll get someone to pay me
to design a language that combines the best of Forth and C.
Then I'll be able to leap wide instruction sets with a single #ifdef,
run faster than a speeding infinite loop with a #define,
and stop all integer size bugs with a bare cast.
More of my delusions:
