IRC I think the roadblock isn't that they need to be approved, but that they can only distribute in the EU.
Is distribution the only problem? If Mozilla or Google were to make their code freely available on some git forge like GitHub and I cloned the repo and built it myself, would I be able to run it for seven days or something in the US?
nope, one can't get the entitlement -- even just for 7 days dev mode -- just like that.
Dev mode packages are self-signed, aren't they?
Unless it can be distributed it's not worth Mozilla or Google's time to bother developing support.
