This system seems quite similar to sending messages to oneself on Signal/Telegram/whatever. What I like about using messenger apps is that every note gets a timestamp and that messenger apps are, in my experience, more polished than note-taking apps.

Then you’re at the mercy of a third party service for access to your notes.

That depends on the messenger app. Telegram, for instance, supports backing up messages as HTML and/or JSON.
