My strong opinion is yes they are required - the need that brought them into TLS 1.2- does not disappear with the upgrade to 1.3. 

I agree that the majority of the installations should not enable this option - but it would be wrong to make it completely unavailable.

(And I don't understand this crusade-ish attitude towards/against the integrity-only suites.)

My strong opinion is no.  Use TLS 1.2 or earlier if that's a requirement.
