I must ask, is a class cluster really necessary?
No.
It is tremendously convenient though, and it makes possible much
looser link between the API contract and its actual implementation,
which brings *great* flexibility and thus is The Right Thing.
They're the bane of extensibility,
Says who? I extend arrays and dictionaries and strings functionality
every day. Never encountered any problem at all.
for only an addition of some trivial convenience.
Tremendous convenience and flexibility.
Is it not a better approach to have well-defined subclasses,
specialising in particular areas?
Definitely nope. The advantage is that a new release or a 3rd party
code can bring new hidden subclasses, whose advantages you older
applications would exploit automatically and immediately, without you
even need to know and without even recompiling.
