I think you're missing the point. Go and take a glance at RFC 2606 -
it's a BCP which defines the .test, .invalid, .example and .localhost
TLDs.
Of course, some users may want to use .invalid email addresses in
their database, despite their being, by definition, invalid. It's
something that will vary depending on their needs.
