These days OpenRC even has user-services. And writing a simple OpenRC service file is barely more complex than a systemd unit file, maybe even simpler, because it's readable bash, not some declarative DSL.

Obviously there is in no way feature parity between those two, that's the point, personally the one thing I'd like to have is something similar to systemd's timers (which I actually prefer to old-school cron) built into OpenRC, but most other things I can live without.
