While cabal init is something I use, I would prefer to have a separate
tool for calculating my build-depends field.  Something that could
suggest things for an existing cabal project, ideally.  Then I could
run that regularly during development to help me determine what my
build-deps should be and cabal init could suggest I run it (or run it
for me).

While I'm suggesting features I would like, wouldn't it be great if
cabal used the plugin RFC that Simon came up with?

I think that interface is a great way to unify the tools that have
sprung up around cabal such as cabal-dev and cab.

I concur.
