Understanding init freedom? - Lemmy

I’m planning to move over to Guix over NixOS, as soon as my current situation improves and possibly import a new libre respecting laptop (Star Labs is thankfully available in India). I do have a very old laptop with a Celeron processor and 4GB of RAM with Guix installed already, and what has come to my attention is that it uses shepherd. I’m not actually against or for systemd, in fact, I am not really sure why I should even care - maybe it is because I’m still not on to the level of a power user. Since I’m starting to learn kernel basics to prepare for GNU/Hurd contributions in the nearest possible future and shepherd seems to be what the GNU folks will be using, is there any reason why I should even care about the freedom of init system?
