Well summarized. It's amusing to read Brave on their unsupported list, since it's just Chromium with privacy features built-in. They wouldn't be able to tell, non-invasively, since it self-reports as the most boring, common version of Chrome that it can. Actually, privacy features that break sites by default if you don't know how to adjust them. Works, guaranteed by our developers and customer support folks, should be a different bar.

So long as they don't active sniff and reject non-approved browsers.
