I use the same techniques to move helper methods into a category

outside, but I understand why there are not.
Depending on the task there might be.
You can use your own hidden subclass, returned instead of the API
stuff, cluster-like. Very convenient, unless your class is to be
subclassed itself.
Also, the extra instance variables can be stored in a dictionary: the
overhead tends to be negligible (not always, of course, but
suprisingly often).
(Matter of fact, I would advocate to change the runtime to base *all*
instances on a dictionary /more precisely, a special hashtable/,
which would vastly improve the flexibility, allow for much better
interface/implementation separation, and also remove the one
fragility ObjC has, but that is definitely beside the point at this
moment :))
