We already have browser data for image-orientation support (https://caniuse.com/css-image-orientation). However, separately we should track which browsers support from-image as the initial value, which is a recent change to the spec.

IIUC, this was added in:

• Edge/Chrome 81 (https://www.chromestatus.com/feature/6313474512650240)
• Firefox 77 (https://bugzilla.mozilla.org/show_bug.cgi?id=1607667, https://bugzilla.mozilla.org/show_bug.cgi?id=1616169)

Safari has had partial support for quite a long time. I say partial because, in older versions (13.3 and below), orientation is only applied to images which are inside the DOM and visible (test):

After running some tests, I believe Safari has full support starting from 13.4 (test). This ticket might be related: https://bugs.webkit.org/show_bug.cgi?id=89052.

I'm not too sure about other browsers. I might need help collecting this data.
