"Google's own documentation"... uh oh, first time?!
The first archived version of this page containing the "can't do" list was published Nov 2024. The email is about a change "making it easier" to be rolled out July 2025 so I would not bet someone else's money on this page being up to date. We'll find out I guess.

My normal "Google's own documentation" experience is the other way round - to be told something is possible when it certainly isn't.
