This is a tracking bug.  The only thing you should be doing is filing other bugs and adding them to the dependency list, if they're architectural issues.

The last needinfo from me was triggered in error by recent activity on the bug. I'm clearing the needinfo since this is a very old bug and I don't know if it's still relevant.
