I had been holding off out of laziness but all this does is give me more time before I transition to fastmail as well. Google is not offering any assurances they won't do something similar in the future. And renegging on the free tier I simply use for email has left a bad taste.
That's definitely within a reasonable deletion windowpz but also maybe up against the edge of it - try yelling really loudly (tweet @AskWorkspace, ask contacts/friends, etc, basically move now) and you very well might be able to get it back.
(I see there's an email address at the bottom of the link in your bio FWIW, just in case someone might consider reaching out that way)
