They can't use this feature to enforce only Firefox. Firefox doesn't have support for this feature, they really don't offer anything like Chrome Enterprise. Its just as much a feature of Chrome Enterprise that Workspace leverages rather than only a feature of Workspace that leverages Chrome.

You can still use Firefox with Workspace though, but if you want the management features of Chrome Enterprise you need to use Chrome Enterprise. Firefox itself just doesn't even begin to offer the same kind of endpoint verification.

With Firefox today, how would a web app have any serious clue the client was running approved versions of Firefox configured in approved ways on approved hardware with approved OS configurations? It wouldn't, and I take it Firefox wouldn't bother implementing that kind of technology. Which is fine, but if the customer wants to be able to ensure a certain kind of policy compliance that's just not possible when using Firefox. And that's just as much if not more of the ball being in Firefox's court as it is Google Workspace's. There's nothing for Workspace to even interface with at all from the Firefox side to ensure policy compliance.

Its like asking "can I print on this printer with this app?" when the app itself doesn't even have a concept of printing things. The basic underlying feature set just doesn't even exist, before we're even talking about some form of platform compatibility.
