The nature of the login manager would have to change fundamentally;
from a binary behaviour to something rather more complex.

It'd have to be told about the nature of "nologin". Doing so
consistently requires standardisation or flexibility; or both.
I don't know if PAM has any outputs other than true/false which
would be of use.

Problem is early termination; you get a login, some text displays
and the login manager re-appears.

Remember; you may not be sitting at the computer that's providing
the login manager or running the window manager.
