I would recommend we wait for 1.39.5, but if there is a consensus to be bold, I don't see why it could not sneak in 1.39.4.

For more details, see the Texture asset color space recommendations.

• All names are now based on color interop short names
• Deprecated names are now labeled as such
• Unit tests still covers all names even older legacy ones
• Introduced lin_ap0, lin_rec2020, and srgb_ap1 color spaces
