Have you ever considered trying something like VRCFury's Parameter Compressor?
vrcfury.com/components/o...

I think if someone wants to crash someone / lag someone out they wouldn't go through the effort of using your camera shader for it.

I'd assume there are shaders made just for that, which would be way quicker to set up for such purposes

That's super neat, would be fun to have that as a camera filter^^
Are you planning on releasing this publicly at some point?
