Why some of us don't is that applications drive the operating system,
and the last successful commercial operating system that was actually
brand new was probably 16 years ago.

Windows 2000 brings along the baggage of DOS, which brought along  the
baggage of CP/M.  VMS brought the baggage of RSX.  AS/400 brought the
baggage of System 36 and System 38.

Additionally, it seems doubtful the assembled multitude could
agree on a feature set.  File versions, security constraints,
file naming, hardware platform, etc. are all sufficient to
bring to the discussion more heat than light.

Choice of implementation language does not give all those qualities
to an operating system.  It may make achieving them easier, but it
does not even guarantee that they are possible.
