>>>Yes, Google knows this is a new Google Workspace account using the same domain as the old one.

I agree it knows that, but it doesn't know:

>>>It's a different bob@DankStartup.com, and in fact a completely different DankStartup.com. Google shouldn't conflate the two.

How should it verify that? Should it? If you buy a domain that was used ten years ago, do you want google to say "well, we can't let you use contact@newDomain.com, someone used it previously and it may be confusing".

>>>I'm certain you wouldn't want the new owners to then have access to your Slack or any other data, just because they have the same domain name.

Maybe nobody should be using domain name and/or email address as authentication, but that ship has sailed in 100 different ways.
