No, this is required for forward compatibility.  Implementations that send extended parameters like capability advertisements (i.e. CAPTCHA support or something) shoudl not be broken hitting older implementations.

Subject: [OAUTH-WG] Ignoring unrecognized request parameters
 

 
In core -23, the last paragraph of section 3.1 now says:
 
                The authorization server MUST ignore unrecognized request parameters.
 
In -22, this said:
 
                The authorization server SHOULD ignore unrecognized request parameters.
 
In a security protocol, it seems unreasonable to require that information be ignored.  As I see it, it SHOULD be legal to return an error if unrecognized information is received.
 
Why the change?  And can we please have it changed back to SHOULD in -24?
 
                                                                Thanks,
                                                                -- Mike
