What's obvious is that you're trolling and that you are bent on "winning an argument".It was obvious that anticapitalista only guesses that some packages "may depend on libsystemd0"
and that "There may be other packages that need to be made systemd-free, but who knows."
No one has had the time for, nor the need for, inspecting and scrubbing 10,000+ debian packages.
Until someone reports "Hey, I tried to install packageXYZ today and can't b/c it depends on packageQRS, which in turn depends on systemd"
why should we expect anticapitalista to know / care about the dependencies of packageXYZ ?
Your expectation that maintainers should proactively patch every "packageXYZ",
moreover every subsequently released version of every "packageXYZ"
represents an unreasonable "philosofical" (sic) demand.
