in fact I don't see why this is "not implemented" at this level
since with WSF we can process any method in the handler

now, if this is related to WSF_RESOURCE_HANDLER_HELPER   then ... maybe this code should not be part of WSF_METHOD_NOT_ALLOWED_RESPONSE  but be specific to the later _HELPER class ...

however we could keep that recognized_methods in  .. WSF_METHOD_NOT_ALLOWED_RESPONSE
but maybe make it an attribute
and add a set_recognized_methods (...)

so that by default any method is implemented for WSF_METHOD_NOT_ALLOWED_RESPONSE
and we can pass the recognized methods where needed


It seems it could be set from WSF_DEFAULT_ROUTER_RESPONSE ... eventually you can redefine WSF_ROUTED_SERVICE.execute_default (...)


well ... this part need to be reviewed I guess.

Could it be excluded from this pull request, and make a new pull request just for this one ?
