Yes, we also need #972 for GHC 9.8/9.10.

Hm, I think it's a fine constraint to not allow two formulae with the same name to be installed at once, but I think the error message should indicate that...

Feel free to rework the issue body, the template seemed really strict so I didn't want to "break the rules"
