what about UToY8(clip clip) and VToY8(clip clip)?

UToY and VToY was already there

so for 16 bit/float will have a new UToYx and VToYx or UToYUV400 and VToYUV400 to output in HBD?

Unfortunately UtoY and VToY is reserved already, and works with 16/32 bit. They do not truncate to a Y8/Y16/Y32 clip.

So UtoY8 and VToY8 is silently working like UtoY16/32 and VtoY16/32. The result clip is greyscale one.
I did not like the names like UtoLumaOnly, etc... so it remained with the Y8 ending, until someone finds a proper name for it and everybody agrees with it
