Is creating a new LDraw primitive allowed?

Is creating a new LDraw primitive allowed?
I'm working my way through addressing issues identified in some stickers I have submitted. One of the suggestions is to use a primitive instead of some quads.

Using "Rings and Cones", I can see some primitives with a suitable radius once a scaling factor is applied. However, rather than wanting a ring, I'm looking for a partial ring. While one of the primitives (3-16ring14) I could use is already available, a second one (3-8rin21) is not. I have played with PrimGen2 to generate the second desired primitive locally.

My question is, if I'm modelling a part and need a currently unavailable primitive, am I allowed to simply define the appropriate primitive (using PrimGen2) and submit the primitive through the parts authoring process? If this isn't allowed, is there an an (official) alternative way to get a new primitive created?

I do have an alternative where I can use a different primitive and apply a scaling to it but the ring segment ends up being too "thick" compared to the actual sticker. My preference is to try to model the sticker with the ring segments having the actual measured thickness.

No problem to create new primitives...
BUT primitives in patterns are interesting only if you are able to border them with other circular primitives (chrd inside, ndis outside). Otherwise it's better to stick to plain triangle/quads

Yes, make as many primitives as you want, but they must be within the primitive standard, if you want to upload and use them.
Primgen2 will only generate a standard prim if you change the size, not the width.

Note also that the ring primitive you want might be named differently. Older ring prims could be named using only "ri" or "rin" instead of "ring". New primitives must use the whole word "ring", in the filename.

I set you on my list of possible spammer and if "1% variation is found" I'll block you immediately.
