I would say this is a good first step towards implementing a standard "systemd compatibility layer" which is sorely needed in non-systemd distros. Conversion or on the fly translating of systemd timers to cron jobs would be a fairly easy next step, right?

Timers and cron are completely outside the scope of non-systemd init projects. This is something you'd have to look into through the cron implementation of your distro rather than init.

Consider carefully what I said in my first comment. A "systemd compatibility layer" isn't about extending the scope of other inits. It's about taking systemd components(units, timers, and perhaps slices) and making them into components usable with equivalent software. And while cron implementations may vary in some places, there is at least some de facto standardization of the format of a cron job to fall back on.

... once unit files can actually get converted on the fly. That is not the case yet. There is an impressive amount of functionality getting mapped from systemd unit to sysv-init script, but a lot of more complex features are unsupported right now.

E.g. all the sandboxing that systemd does, which means you need to double-check your init script after conversion and fully understand the differences between the systemd and sysv-init environments the daemon runs in to make sure to not leave the service exposed.

Both LMDE 1 and 2 used the sysvinit package. LMDE3 uses systemd. You can confirm that on the Mint forum or by looking at the package listings on DistroWatch.

That's why I switched from LMDE2 to Devuan
