I still see many skins using the old spinner skin. My guess is that it's just impossible to achieve the desired effects with the new one, or even impossible to embed in any other color scheme.
It would be nice if the colors of the new spinner could be customized in the skin.ini
SpinnerGlow
The tint color for the glow image.
Current forced default: blue
SpinnerGlowBlink
The tint color that is applied to the glow image whenever a new score is spun.
Current forced default: white
SpinnerMiddle
The tint color that gets applied to the middle image.
Current forced default: red
If you don't know what i'm talking about, i made an example skin demonstrating the color behaviours.

Just try it out on any map with spinners. for example https://osu.ppy.sh/b/829238
