Sure, I can get behind that, as it's a pretty pragmatic approach. 
Realistically we're already using 501 in the code in a few places today 
anyway, so my concern about it possibly breaking some one can't be true.

It's probably worth noting that we should reset the template in 
webob.exc.HTTPNotImplemented before throwing it though, because it could 
cause confusion if it ever manages to bubbles up. I've seen the html 
templates bubble up on some manual fuzzing I've been doing recently.

code included for reference
....
class HTTPNotImplemented(HTTPServerError):
     """
     subclass of :class:`~HTTPServerError`

     This indicates that the server does not support the functionality
     required to fulfill the request.

     code: 501, title: Not Implemented
     """
     code = 501
     title = 'Not Implemented'
     template = Template('''
The request method ${REQUEST_METHOD} is not implemented for this server. 
<br /><br />
${detail}''')

But even if you want to argue semantics of the definition the point stands the in this case 501 is a more meaningful error to receive than a generic 400. There are myriad other reasons a 400 could be returned and then a consumer of the API has to deal with parsing messages and other nonsense. A 501 has only one reason it would be returned by that API and is therefore much more useful to consumers. I would hope that's reason enough to make the decision.
