HDRP looks amazing, but for games, especially things like VR, it is pretty unrealistic to get the performance needed with HDRP, so URP is becoming VERY popular. Most of my other assets are URP at this point. Sure, I can download the standard version and "upgrade" to URP, but it looks nowhere near as good as URP should look. Conversely, I have tried without success to downgrade from HDRP to URP. This would I guess involve a lot of manual work on materials, so URP versions would be incredibly useful!
