I strongly disagree and note the obvious internal inconsistency in your
argument (such as it is):

In the direction you seem to be headed lies the true and vivid idiocy of
the Debian shell, which is *larger* than our shell (depending on platform
and compiler flags, etc.) yet strips out functionality every other modern
shell offers, such as command line editing -- for purely doctrinaire
reasons, since after all, these features were in what they started with.

Removing features as a way to enforce some kind of religious notion of
programmer discipline (which seems to be what the rest of your message
suggests) is dumb.  I would like to see our shell remain about the size
and speed it is (both of which are best-of-class) but gain something close
to feature parity with ksh.  I think Robert's work is getting us there.
