The following policies exist in chromium [1], but have not been manually registered to appear to end-users in admin.google.com:
a) SmsMessagesAllowed
b) SmartLockSigninAllowed
c) InstantTetheringAllowed

Note: EasyUnlockAllowed has been registered, and does not require any attention. It shows up in admin.google.com as "Allow Smart Lock on Chrome device".

This change is not a chromium change, and is therefore not tied to any milestone.
