Can WebP and SVG be allowed as attached image types?

They're both supported by all major browsers now.

I don't want them. When I save a file, I want it in a format that has far more legacy support, not just viewable by a modern browser.

Granted, I'm not saving nearly as many files in this forum as some, but still feel like we shouldn't encourage use of formats with far lower compatibility. Now more than ever, there are far more IOT connected devices, should not break their functionality under the assumption they will get same browser updates as a phone, or desktop/laptop.
