Not sure there are enough users to justify taking actual mozilla engineers off core problems that are everyone's problems. There is a maintenance burden and associated cost for every feature that mozilla adds to their core product. I think they would rather make the browser extension backend robust enough to allow for those types of extensions without sacrificing stability, performance, and security.
