Part number for double injection and assemblies

[Willy Tschager]

The older 30152: Assembly
The newer 10830: Dual Injection.

As the Trans-Red is only available as the 30152 variant, I would go for a ...c01/...c02

Brickset "Element count" field makes it clear:
30152 and 90463 are assemblies (Element count=2) -> c01

10830 is Dual Injection (Element count=1) -> p01
According to images, 30152 and 90463 have thin edges, but 90463 has a thicker glass, while 10380 has thick edge/thin glass

If the Element count would count determining if it is an assembly or a multi injection how would you rate these:

https://brickset.com/parts/design-52210 (Element count=2)
https://brickset.com/parts/design-2634 (Element count=1)
https://brickset.com/parts/design-47847 (Element count=5)

I tried to remove the lens of the 30152 - no chance. It is further more inserted seamlessly.
