Sounds like a good idea. Installing a specific version of Python nowadays is easy enough and there a few tools that make this experience as smooth as possible. For example, uv uses prebuild pythons for many OS to speed up the installation and to reduce the risk of build errors (see https://github.com/astral-sh/python-build-standalone). I very much doubt that sage will ever reach this level of smooth user experience and sophistication - nor should it be an aim of a computer algebra system to worry about this.
So +1 if it is replaced by proper documentation using a modern and standard tool (uv?) plus a few alternatives that usual work (system installation, pyenv).
