But that's (+ AV1) about it. I wouldn't install edge just to test whether there are any files encoded with these codecs. (unless there are a LOT of media encoded in different ways e.g. youtube)
Just test on chrome and keep in mind to avoid AVIF
…Which you should be using the picture element or image() to fall all the way back to PNG or JPEG in most scenarios anyhow. New & improved formats like JPEG-XL should be considered ‘enhancements’ rather than relied on.
Don't remember what it was exactly, but I did run into some obscure scenario (something with tab focus I believe) where Edge had a bug that prevented my code from working.
Just spin up a VM for testing Edge, the differences are small.
