nologin field doesn't work with proxying. You'd have to return neither
"proxy" nor "host" field. With host+nologin it would be treated as a
login referral:

Of course it would be possible to add yet another check where proxy+host
+nologin returned would be treated in yet another way, but that gets too
confusing..

I guess it was a mistake to use "nologin" for login referrals in the
first place. And I guess just about no one uses them anyway. So them, so
it would be possible to change this behavior..
