RFC 6665 tells

   Implementations conformant with the current specification MUST treat
   an incoming 202 response as identical to a 200 response and MUST NOT
   generate 202 response codes to SUBSCRIBE or NOTIFY requests.

So should default behavior be 200 response.  At least new users of the
module would expect is it works according to standard out of the box.
