NEP 29 just defines the minimum supported Python version, having a longer support window is equally NEP 29 compatible.
Since we depend on numpy, sage-the-library inherits NEP 29. There isn't really anything to vote on here. As far as sage-the-distribution goes, we should tie the support window to popular distros. Ideally by liberally calling "conda install python" whenever the distro python is too old. Its unclear to me if this or the vote thread is about the library code or the distribution...
