Ok, let me rationalize this a bit more.

If someone files a bug that happen to be changes as enhancement but the maintainers or the bugsquad, is so clear cut that a developer alone can consider it without involving product manager or change in the development plans, if it doesn't require votes or much discussion and perhaps even a patch can be attached... then there is no question that bugzilla is the place.

If someone has a proposal that he can't fix himself with a patch, or can't even describe accurate solutions, would need further discussion, perhaps votes and support, and anyway Nokia developers wold need to accommodate plans and discuss with product managers... then this is clearly something for the Brainstorm.

In practice I think it's easy to detect what proposals go where.

And in practice we could

- document this
- resolve new proposals landing in bugzilla as Invalid pointing to Brainstorm
- do the same for current enhancement requests that fall in the second category and are not in the plans currently
- keep in bugzilla the take-or-leave specific enhancement requests plus those that can be resolved soon based on current plans
