1) systemd is the wrong place for the safety measures. rm is also the wrong place for the safety measures.
2) remounting a mounted FS is a non-trivial operation with lots of corner cases. What happens when another program is accessing that FS at the same time?
It's simple--the kernel needs to be fixed. Access to EFI should require special sequences to cause writes.
systemd folks aren't going to ask for it because Linus will simply piss and moan and close as WONTFIX/NOTABUG.
