The government(s) need to force Google to obey web standards that are set by an industry consortium. One that also has small player participation as a requirement.
If Google is strong arming or pushing ahead their own agenda, the standards body should have plenty enough votes to veto.
And for teeth, compliance should be a requirement for Google to even be allowed to have its own browser. If they break it, no more browser for Google.
Google mostly does obey web standards that are set by an industry consortium (WHATWG, W3C, or in the case of JavaScript EMCA).
Chrome has the best compliance with standards of any of the big three (see wpt.fyi) - which is not surprising, because they also have the most engineering time dedicated to their browser, and the most people working on standards.
These bodies require buy in from multiple vendors, but generally not unanimity. That said, browsers can and do ship things which haven't been standardized (e.g. WebUSB, which is still only a draft because only Chrome wants to ship it). In a lot of cases this pretty much has to happen pre-standardization, because it is difficult to come up with a good standard from the ivory tower with no contact with actual use. Chrome is unusually good about working in public to develop specifications for such features even when other browsers aren't currently interested in shipping them.
I don't know what problem you think this proposal would solve.

That is, if there's a promotion, or a company bet, or a need to establish/secure market dominance for one property or another, Chrome dumps a scribble on a napkin, barely engages in any conversation, and ships to production within a few weeks after dumping said scribbles.
Once it's out there, it couldn't care less what other browsers vendors will say. Dominant market share and an army of developers who never bothered to learn about standards processes will make sure that this is now a standard.
The government and most voters don't even know what a file is. They can't even vote in favor of their own basic needs like health care. Do you really think this band of incompetents should be empowered to strangle innovation?

And there's no way, in general, to differentiate you (who I'm assuming to be a good-intentioned actual-expert) from someone who is either (a) not an expert or (b) not good-intentioned (i.e. a lobbyist) - so this offer is effectively useless, and the more general point of "there are experts that can help" is invalid.
I've been thinking about this problem a lot, because it is one that needs to be solved. But it's more complicated than just saying that "experts from the community can offer to help draft regulations" because the problem of how lawmakers can trust those offering help is very difficult.
...and that's assuming that the lawmakers are operating in good faith and accurately representing their constitutents' interests, which there is scientific research[1] that indicates is not true.
We have to let Google do whatever they want, lest we strangle innovation. The people we trust to literally run the country, to build, operate, and maintain nuclear weapons and submarines - they can't be trusted with things like files.
