I think this would be a great deal of work for little useful benefit.

I'm saying that I don't believe there is anything in Policy right now that
prohibits such behavior. Not every possible bug is proactively ruled out
by Policy. Many are left to the common sense of the maintainers. The
purpose of Policy is to document the correct course of action in which
there are multiple reasonable choices or where we need a ruleset in order
to produce an integrated and consistent distribution.
I personally don't see a current need to state in Policy "don't add shell
builtins that override common commands without providing the features of
those commands"; I think that problem can be adequately dealt with by
normal bugs and the application of common sense.

Okay, in that case I believe we have a fundamental difference that I don't
think spending further time discussing is likely to resolve.
I disagree with your proposal and do not believe it is the direction we
should go.

The absence of a requirement in Policy is not a positive declaration that
something is not a bug. I do not want to document every possible bug in
Policy; I don't believe that's a useful use of resources. No one has to
my knowledge uploaded a shell intended for use as /bin/sh that overrides
debconf in random and unpredictable ways, and I believe the likelihood of
anyone doing that and then being sufficiently convinced of its technical
merits as to demand citing chapter and verse of Policy to resolve the
situation is exceedingly low.
