These handlers need no special treatment. ASP.NET runtime should be and 
according to my experiences is able to receive HttpExceptions with 
status codes from handlers/user code.

Only 403 and 404 codes are treated specially, that means a more 
destrictive error page, but that should not make any distinction based 
on the origin of the exception, just the status code.

No maintenance requirements come with these two handlers. They just 
should be treated just like any other external handler. Their sole 
purpose is to throw HttpExceptions with the respective status code.
