Because most maintainers love it compared to Sys V scripts.

In the end, users might complain about purity of things or something but the mainteners are the ones doing the work maintaining all that and end up deciding what gets used.

Honestly, I'm rather outside of all that stuff and I had my share of problems with systemd issues but that's mostly because I've been using pretty old systems anyway with thus older and buggier versions of the code. And I also remember the pain it was before unit files to get those sys V scripts working correctly. From my perspective, both systems had weird bugs I had to track but systemd clearly wins on the "creating a new service" part.
