Hi,
what happens if an encrypted filesystem (plain, no LUKS)
next time is opened accidently with a wrong password,
and new data written to it? Will the filesystem then become
damaged/unusable?

What typically happens when you use a wrong password is that the cryptsetup create/open command is indeed successful, but mounting your partition will fail (because the filesystem is not detected). So you have few chance to accidentally damage a filesystem, even in plain mode.

I didn't try this out, but I know the create/open command accepts
any password for an already existing encrypted filesystem
since no metadata is stored with such a "plain" volume, right?

Right, but this does not mean that data will look meaningful.

Best,
Quentin
