I gone this route.

I got different markdown editors on different devices and didn't want to use a public / cloud hosted git repo for my notes.

It works fine, as long you don't get in contact with iOS.

I got many devices and often let it sync my phone when I'm at home, because I'm struggling already enough with battery lifetime.

I also got it running on one of my dedicated servers, so I got an offsite backup, with systemd you can set it on autostart after an internet connection was established, so I don't really have to manage it anymore and I only see it basically in the logs of the packages that I update.
