There is no black or white answer. Each decision on whether to inherit or
compose features will have to come down to performance testing to be able
to measure the pros and cons of such decisions. We can sit here and
pontificate on the ideal architecture until we are blue in the face but
without performance tests to back it up then its just hot air. The answer
will likely be both, with careful consideration as to how many new objects
we introduce into such a huge component like UIComponent while continuing
to increase the speed and not weight it down.

I'm not really sure what you're trying to get at with the rest of your
reply, sorry.
