I asked Google during an RFP when I can use my paying personal workspace for things like reminders or Google Home (and invite my family). It was "right the corner". The corner is now what, 5 or 7 years away.
This is a company I am with for a bit less than 20 years, but I will leave.
I’ve seen another variation of this at work: we have two domains registered with G-Suite, Google professional services ghosted on a consolidation process, and this means that only one of those sees the licenses. They block all access to services when you’re logged in to the other domain, even just to view a third-party’s shared document unless you buy a second license for the same person. This has been a slow gravitational win for Office 365.
I suspect this is because they can't use Workspace data for improving the models.
