It's documented in the EIEIO manual that the :protection slot has no effect.

(info "(eieio) Slot Options")

‘:protection’
     This is an old option that is not supported any more.
[...]
     This protection is not enforced by the code any more, so it’s only
     useful as documentation.
Added tag(s) wontfix. Request was from Noam Postavsky <npostavs <at> users.sourceforge.net> to control <at> debbugs.gnu.org. (Sun, 15 May 2016 15:19:02 GMT) Full text and rfc822 format available.
