What I meant is that it would break the CUDA package for Python and support in things like Tensorflow, obviously. Not CUDA itself.
You can't just "install new version" of those packages unless Nvidia supports it, unless Tensorflow supports it, unless OpenCV works with it. If you have ever tried to build Tensorflow from source, you would know what I am talking about.
I have, on python 3.7, and it works fine with the entire CUDA matrix from 10.1 to 11. So your point has theoretical merit, but in practice, it's not a real problem as compatible versions of those packages are readily available.
