I would make it monthly or quarterly not weekly

By the way Google has had this for a while and I signed up for it back in 2018 or so.

they check in it feels like quarterly at most

For version 1 we decided for the check-in to be weekly because it can still take 13 days for the Switch to tell the lawyer and/or the 2IC where our master keys are held. Thanks for the link, this isn't locked to google accounts, it's more so for the 2IC to ensure business continuity with servers domains Dropbox etc.
