Consolidate Chromium

[o-t-w]

Because Microsoft Edge is a popular browser and there are occasionally minor differences with Chrome (e.g. Edge didn't support AVIF images for ages), it probably makes sense to continue to list it seperately. However, other Chromium browsers are neither different enough nor significant enough to justify their own entry. Maintaining seperate data for more browsers makes contribution harder. There are dozens of browsers based on Chromium (Arc, Brave, Vivaldi, Opera, etc). I'm a user and fan of both Arc and Brave but as a developer it makes it harder to scan and assess the data when barely-distinguishable browsers are listed seperately.
I suggest that data for Opera desktop is removed and the following issues are closed #2964 #2749

In the course of my whole career I have never heard a stakeholder or developer ask about Opera support.

IIRC, both Opera and Edge were initially begun as non-chromium browsers before becoming such. Edge became Chromium-based since 2020

It would be nice if Chromiun, Firefox, and Safari was the first 3 in the list at the very least.

Ideally, you could maybe remove all the other ones and instead create sub-items. Click on Chromium and you'll see what's supported in Chromium proper and then optionally be able to see if Edge, Brave, Arc, Chrome, or whatever other Chromium-based Browser supported the features.

The current state is very unfortunate at least, because it makes it seem like Firefox and Safari is "among the masses" while in reality they're the only ones not among the masses.

Yes that is true. Developers don't need to see ancient historical browser support data though. Opera switched to Chromium many years ago. A vanishingly small amount of users are stuck on the old pre-Chromium version of Edge. Support data for those browsers just isn't relevant anymore, which is why they could both be wrapped into a single Chrome/Chromium listing.

Samsung Internet needs to remain its own listing because it is always far behind the current version of Chromium and is a relatively popular browser.
