Hi:
Since newconfig appears technically superior, what are the issues that
are hindering its acceptance?

Of course, I completely agree with you.
The reason I prefer newconfig is it actually can support dynamic
configuration better than the new-bus. All features which new-bus has
can be implemented on newconfig, too. And, more. (See the description
about on-demand dynamic loading in my previous post.)
Furthremore, newconfig does static configuration better than the
new-bus, and newconfig has a option which removes dynamic configuration
entirely from kernel. New-bus apparently doesn't have this option.
So, which is flexible ? :-)
