Well, that's the problem, and it's the reason why 603 is so commonly
used. This is a situation where the current request has failed, but
there is no indication that repeating the request will also fail. 403
means that the request should not be repeated without either changing it
or authenticating as a different entity, which is a different scenario.

It is very likely that there is no standard-defined 4xx code for 'cannot
process this call right now', only the 5xx and 6xx variants.
