Something else I noticed in the SAMD manual.

> To issue a command, the CTRLA.CMD bits must be written along with the CTRLA.CMDEX value. When a command is issued, INTFLAG.READY will be cleared until the command has completed. Any commands written while INTFLAG.READY is low will be ignored.

That raises the question whether we should worry about the INTFLAG.READY bit for _any_ CMDEX command, including PBC.
