Proposed ghc-pkg and cabal feature - right list?

There doesn't seem to be a mailing list for Cabal itself, so I'm
posting here. I came up with an idea for a small feature that I
believe would make a useful addition to ghc-pkg and Cabal. I'm
willing to implement it myself, but I have had some previous
experiences with other projects where I did some work and then the
maintainers said "sorry, not interested", so I want to gauge interest
before I start. Who should I talk to?
The feature itself is this: Arbitrary key-value pairs in Cabal
package files and the installed-package database. The use-case is for
an application supporting plugins to discover installed plugins
compatible with it, interrogating these fields through the GHC API.
For example, my content-management system FruitTart could enumerate
the list of installed packages looking for packages which export a
field "fruit-tart-plugin-interface-version" with a numeric value
matching the interface version it's expecting.
Once again, I'm not asking anyone to do this work for me - I'm eager
to get my hands dirty and do it myself. I just want to find out what
the process would be to get it accepted, once it works.
Thanks in advance,
