The above paragraph is simply incorrect. Your last proposal also included
deprecation warnings and a future backwards compatibility break by removing

If you now say you're not proposing steps 3 and 4 anymore, then you're back
to what I called option (2) - duplicate keywords forever. Which for me is
undesirable, for reasons I already mentioned.


P.S. being called short-sighted and damaging numpy by responding to a
proposal you now say you didn't make is pretty damn annoying.

P.P.S. expect an identical response from me to future proposals that
include backwards compatibility breaks of heavily used functions for
something that's not a functional enhancement or bug fix. Such proposals
are just not OK.

P.P.P.S. I'm not sure exactly what you mean by "default keyword". If layout
overrules order and layout's default value is not None, you're still
proposing a backwards compatibility break.
