I think Heic compatibility outside of the Apple universe are too problematic to be useful when coming straight out of the camera or iPhone. I’ve read that Google dropped support for jpeg-xl maybe because rendering time issues over the compression… so JXL may be lost in the wilderness for a fair amount of time.
I think a workflow (developing AND keyboarding) using Nitro initially with export of Heic files into Photos library and moving the raw (or other original) files to a dedicated catalog (Photo Mechanic, Photo supreme, xnView) with keywords hopefully intact will work pretty well for me.
thanks
