Is it possible to specify per browser permissions?

So, the context around this question is that my extension leverages the tabGroups API, which isn't available in Firefox, and doesn't seem likely to be implemented for a very long time, but I would still like to be able to release something for Firefox.

I know that I can add logic that only executes code on certain browsers, which is checked at compile-time, but is there anything I can do to have the tabGroups permission (for example) only be requested in compiled manifests targeting a specific browser?
