In a similar way Affinity supports OCIO it would be great if Adobe atleast kept up. The plugin someone has made does not work properly and is far from ideal, it requires LUTs to be made for each possible combination, its not fluid at all and the result is often incorrect.
Full 32bit support is pretty vital in general for everything in PS
Photoshop is the industry leader and has been for years but if you don't keep up with the times you will loose your user base.
