Device lists contains user ids from unencrypted rooms

[fred84]

According to the docs, changed and left in device_lists should contain user ids from encrypted chats :

List of users who have updated their device identity or cross-signing keys, or who now share an encrypted room with the client since the previous sync response.

However, both lists are populated without taking into account if a room is encypted or not. Sytest 06-device-list.pl also ignore "encrypted" property of a room.

Who is right: current implementation or docs?

P.S. Related sytest issue: matrix-org/sytest#1280
