Well, there is a way to stack error handlers, although it's not pretty:

codecs.register_error("surrogates_then_replace",
surrogates_then_replace)
That mitigates my arguments significantly, although I'd rather see
something like errors=('surrogates', 'replace') chain the handlers
without additional registrations. But that's a different PEP or
arbitrary change. :)
The first version of PEP 293 changed the errors argument to be a string
or callable. This would have simplified handler stacking somewhat
(because you don't have to register or lookup handlers) but it had the
disadvantage that many "char *" arguments in the C API would have had to
changed to "PyObject *". Changing the errors argument to a list of
strings would have the same problem.
A comma-separated or space-separated string, eg 'surrogates replace' or
'surrogates,replace'? It could be treated as handler stacking
internally.
