devuan has set in stone they will never implement age verification, i can use sysvinit no problem specially now that my custom session process is fully capable of managing my x session and user-services, i just need to write documentation now... but since i wrote that i will never need systemd nor need to look at stuff like runit, openrc, s6 or dinit, maybe i should look into making my stuff more integrated with sysvinit or at least making use of the libraries that debian has for initscripts, but that will definitely be for later.
if at some point the freedesktop.AgeVerification1 interface becomes a requirement for non gimped normie-net i'll just write my own daemon that spoofs that shit, from what i've read of the spec it ain't hard.
