Essentially -- yes. We have never had such a consistent interface,
and we should be loathe to carefully consider the consequences of
forcing one.

Further, it should be done in a careful thoughtful fashion. Requiring
a consistent interface is not a good reason to change one of them and
leave all the others.

I do not understand this argument.

It (and perhaps more importantly PCMCIACISDEBUG) do not add zero value.
It may be important for non-developers to be able to turn them on
to perform useful debugging and useful communications with developers
without requiring custom kernels.

Perhaps this is an architectural flaw, but if so, that flaw should
be correced before the useful mechanism is removed.

You seem to be ignoring my assertion that these are valuable to
non-developers. Do you disagree? Do you find my argument insufficient?
Explain, please.
