Could Google Contacts sync break any day now?

[Glen Ditchfield]

AFAICT libkgapi still uses Google Contacts API version 3.0
(https://developers.google.com/contacts/v3) which says

Warning: The Google Contacts API is now deprecated and is scheduled for
sunset on June 15, 2021. Apps should instead use the People API. Get
started with the migration guide. For our official statement on the
deprecation please read our service announcement. 

Bug 439285 is open for this.

Is anyone here looking for a project?
