Remember, we don't treat the LUKS device as a separate device. If they
want to delete a partition that has a LUKS format, then can. If they
just want to remove the LUKS formatting (and implicitly destroy the
LUKSDevice) then they simply deactivate the "Encrypt" checkbox in the
partition editor.
Checking the mutability of the LUKSDevice is the only thing that makes
sense since it is what will contain the formatting we are interested in,
such as pv, mdraid, &c.
