It does add another layer to the process though. For enhancements, the additional layer brings enough benefit to make it worthwhile, but I'm not so sure it would help bug reports.

Enhancement requests tend to be big ideas that require larger scale design and planning work before eventual implementation. Brainstorm makes the design and planning discussion and voting process easy and accessible to end users, as it should be. Then, at the end of the process in Brainstorm, a well-defined enhancement request can be placed in Bugzilla for the implementers to target.

There's real benefit there, as Bugzilla's discussion capabilities are limited, and it does not provide the granular voting capability necessary to refine an initial enhancement idea into a plan. Brainstorm and Bugzilla form one of those synergy things.

In contrast, bugs are often smaller, are by their nature more definite (once determined), and should see faster turn around. Discussion is sometimes necessary, but it's usually just to define a bug's effect and cause as clearly as possible to speed resolution and confirmation.

Currently, bugs (and enhancements) exist in both the public, maemo.org Bugzilla and Nokia's own internal bug tracking system. Nokia uses the internal system to hide private details of unreleased hardware and software. So, right now, Andre, for instance, spends time moving information back and forth between maemo.org Bugzilla and the internal tracker, sanitizing as necessary. This is better than it was previously, when reports of bugs at maemo.org Bugzilla often received no feedback at all, but it's hardly ideal. As a long term goal, some folks are investigating solutions that might allow for the elimination of the internal system, which would free Andre up for more productive work.

However, if a Brainstorm-like system were used as the friendly front end for bugs, we'd need many volunteer Andres to move information between that system and maemo.org Bugzilla. It's an increase in work, and it turns bug reporting into a game of telephone, where we risk losing important details.
