What other dev OSs are there?

once privileges are dropped [...] it doesn't appear to be possible to reinstate them

I don't understand. If unprivileged code could easily re-elevate itself, privilege dropping would be meaningless ... If you need to communicate with the outside, you can do so via sockets (such as the bind-mounted X11 socket in one of the readme Examples).

This might be a red flag for Persona service itself as it might contain serious flaws and security vulnerabilities that Cyber criminals are relying on

Persona seems to rely solely on NFC with a national passport/ID, so simply stolen documents would work for a certain duration ...

Too personal to share, but maybe too personal and important to share even with the members of the cloudy cartel, i.e. the Providers. Is exactly why I wrote myba that does full contents and paths encryption before syncing with the lapsable remotes ...

Some things are better public. Some are not ...

Building upon 40+ year old, stable technology that, compared to Wayland, still seems to be in popular demand [1, 2] is the only sensible thing for the lazy maintainer/dev. That's how I felt when I wrote X11-compatible EF*CK emoji keyboard [3].
