As someone else has pointed out, this is only a deprecation at this point. For comparison, support for `cgroups v1` which is being removed in this release, was described as "legacy", and to be removed in a later version, happened with systemd v233 released in March 2017. That's more than 6 years between deprecation and removal. Also, `cgroups v1` systems were marked as "tainted" starting in v248 released in March 2021. Based on that, you've probably got a few years yet before your sysv scripts actually start breaking, and you'll probably get a more visible heads-up a couple of years before it actually happens.
