And please also share why not just use e.g. 256-bit UUIDs instead of v4 128-bit if collisions really are a problem with 128-bit (which i find hard to belive).

I think for the same reasons that 128bit ones can collide, any amount of bits could. I don't have a perfect understanding of the math involved so I could be wrong.
