And with Syncthing's Untrusted Device Encryption feature I can use my VPS as an extra node for synchronization without worrying touch if it becomes compromised without me knowing.
And it hides file names and sizes by splitting things up, which puts one extra layer of difficulty for someone trying to find my passwords file to target. I have a much stronger password on the syncthing directory than my normal type-each-time password to open keepassxc.
