I don't think there's any plan to remove the sysv init script
compatibility from systemd. That should basically continue to work
forever, and if it's working for you, awesome. 

If you _do_ want to convert a script, there's a nice guide over on Fedora

Why would you want to? You can get some nice functionality like
restart-on-crash behavior or resource limiting with cgroups. But,
again, if you don't wanna, you don't hafta.
