It's mostly subjective, I guess.  None of the reasons you've cited
seem at all compelling to me, and if we change this stuff then we'll
all get unnecessary questions next time we make a kernel.  Anyway I
like it the way it is, and I'm the maintainer. :)

I disagree with that.  There are major differences at the
implementation level for a lot of things.

Paul.
