Oh, ah; I thought the above meant "why not Chromium and/or Edge" rather than "why not the Chromium version of Edge."
Yes, I can see why you'd avoid Edge specifically, same as avoiding Chrome specifically.
But that's not an argument against using upstream Chromium (which is, in fact, a browser all on its own, stadnalone downloadable and shipping with several Linux distros); or against other Blink/Chromium-based browsers (e.g. Brave), no? Either choice would get you compatibility with anything Chrome itself is compatible with (in terms of websites; not necessarily in terms of extensions—though the difference is just in the legacy Chrome extension APIs; WebExtensions work fine everywhere.)
