@Danny B.: You split the support column for legacy and Chromium-based Edge, but left the Grade A support cell for the legacy one empty. What does that mean? Same as for Chromium-based, i.e. the latest and previous EdgeHTML version is Grade A? Or no Grade A support at all? (Please add a dash in this case.) Or it hasn’t been decided yet? (A question mark would help.) Please note that I upgraded four Windows 10 computers to version 2004, and probably one or two of them got the Chromium-based Edge, the rest had the legacy version even with version 2004, so dropping Grade A support for legacy Edge is probably too early at this time.

I'm still sitting here kind of puzzled about why it needs its own column as there was no rationale given in the edit summary. Legacy Edge will have been bumped off the grade A in another release of Chromium Edge (if that).
At most this needs a note, if it is that large a concern.
There isn't any, I believe.
That’s unfortunate and too early IMO. Do we have figures on how many users access Wikimedia sites using legacy Edge? I think it’s quite a large fraction of all Edge users at the moment. By the way, IE versions are supported for way more time, and the support for the discontinued Presto-based Opera (v12 and below) was dropped more than one and a half year after the release of the last security patch.
IE isn't auto-updating; Edge is. They're not comparable.
If legacy Edge did auto-update to the Chromium-based one, it would be OK to drop support for the former after a short transition period. However, it apparently doesn’t. As I mentioned, some computers recently updated to Windows 10, version 2004, had legacy Edge after the update. Out of the four computers, I manually updated Edge on one, I don’t have access to other two at the moment, but on my personal Win10 computer (on which I haven’t updated manually) I still have legacy Edge, with zero Windows updates and zero Microsoft Store updates available. (There’s no update functionality within legacy Edge itself.)
Hmm, yes, that is unfortunate. However, legacy Edge is only about 0.4%, and below our general support threshold for Grade A; I believe it's not been Grade A for quite a while at this point, and I don't imagine that (perhaps implicit?) decision being reversed.
And how many users use Chromium-based Edge? You know, if all Edge users are not more than 1%, that seemingly small percentage becomes almost the half of Edge users, which is not negligible from this POV. :)
About 2.1% of Wikimedia Web requests are from Chromium-based Edge.
So approximately 16% of all Edge requests are from legacy Edge, or one in six people. That’s not that small fraction… I know that Grade C doesn’t necessarily mean that anything non-basic actually breaks nowadays that feature checks are the primary identification method instead of user agent detection, but I think it’s too early to deprecate this platform. By the way, Edge Legacy as a product is supported by Microsoft for almost half a year from now; I don’t think it’s a common practice to end support for browsers before their vendors do so.
