I.e. there is a paredefined GUID for that partition; if there are
ones, they'd get the same GUID which sounds like a recipe for
desaster to me.

OK, forget that one; Arvin just told me that this is not the ID of
that partition, but the type (that was a one-byte value like 0x83 for
Linux, 0x82 for swap etc.).

Still that doesn't clarify if there can be multiple ones.

Not 100% sure I still remember everything correctly, IIRC Raymund told
me (some 10+ years ago) that some operating systems wipe the contents of
the partition completely when reinitializing bootloader - which
effectively prevents any sharing.

Stefan, thanks for reaching out to Raymund to get this clarified...
