Request for Dot/Point type

I'd like a Dot/Point type that is essentially the Disc shape, but retains its circle-ness no matter the camera orientation. As a separate type it would not need to support the Pie/Ring/Arc subtypes nor the new fancy dashed styles. 

To give some context, I was working on replicating a neat little animation I found:

Which is all fine and dandy until you rotate the camera:

Current solution is to simply rotate each disc to face the camera, but a shader based solution would be nice. 

What about spheres? Discs look crisper and have significantly smaller triangle counts, but the sphere type is effectively what I'm going for.
