I think there's a deeper issue around paying customers being assumed to be businesses. I have a paid Google account for just one reason - using a custom domain with Gmail. This lets me have a wildcard email address, but more importantly, it gives me the ability to move my email address to a different provider if my Google account got caught in an automated system and blocked, so I wouldn't lose access to all the services I've used that email address to sign up with.

If there was a way I could continue to just have a regular personal Google account, but pay an extra fee to use a custom domain with it, I'd much prefer to do that than maintain an enterprise Google Workspace setup with only a single user in it, just for this one feature.
