That would not be much different from a drop down of Mastodon instances then?

For both it's a bad way of doing it because people with their own domain can't use it for email and the Mastodon one would be too long to select something.

I meant that the comparison to the email is not adaquate because the number of common email domains had been steadily decreasing (and I hate it).
