Right.  I don't believe there is a great answer for this one-- at least 
without asking developers to "follow a convention".

In the case of that method, the method name doesn't matter.  It is only 
the signature that matters-- even in ObjC.  You specify a name and a 
method to be invoked, and it assumes the signature will be compatible.

But what if we wrapped the various methods that take signatures and 
dynamically created and/or checked and/or enforced the signature at 
that time?

There aren't that many entry points in the appkit that exhibit such 
behavior and every single one of them is precedent to a fairly 
laborious task-- popping down a sheet, for example-- and a few 
milliseconds spent validating API the first time through will never be 
apparent to the user (or developer).
