I didn't want to make it more important :-)
I'm fine with the second occurrence overwriting as it did a while now and
knowing it is not a totally unknown issue.

I had seen the old argument for not moving them out completely in the old
thread - thanks for the link - that was important to understand why they
are still there.
Also found related patches from Keith about that now.

You mean just filtering them eventually while keeping them where they are
so that the old request to have "the base config shows all config options"
still fulfilled - yeah that could be an approach to make everybody happy.
But then it would make for some evil unreadable sed or such, I could live
with it as is knowing it is accepted as-is.
I'll submit an RFC, but hope for someone with more dark magic to make it
nicer.

Kind Regards,
