Geo-tiffs are the go to standard in GIS integration of any property map. Photoshop works really well with tiffs.

Was going to say the same thing; GeoTIFFs are common. But they are a "specialist" format in the way the article is talking about.

Why is GeoPNG not a thing? PNG is based on TIFF's design with various chunks allowing all sorts of metadata storage. It'd be pretty easy to translate GeoTIFF's GIS stuff into PNG. Has that been done?

I asked some GIS experts on Twitter and GeoPNG is not a thing. Most folks seem to think GeoTIFF does just fine so there's no need for it. TIFF's support for more than 3 channels of data is a big help for multispectral remote sensing.
