These are the Python distributions we use in uv (
https://github.com/astral-sh/uv), i.e., when you install Python with uv, you're installing from python-build-standalone. (Same goes for many of the other tools that can install Python for you, like pipx, Hatch, Poetry, Bazel, etc.)
Most of our engineering time on the project over the past ~year and a half has been split into three buckets:
1. Keeping up with upstream CPython. (We're also hoping to upstream as much of this work as we can into CPython itself.)
2. Fixing any / all of the known "quirks" vis-a-vis CPython.
3. Making these distributions as fast as (or faster than) any other CPython distribution.
If you're interested, I wrote a bit about the why / how here when we took over maintenance of the project: https://x.com/charliermarsh/status/1864050698574311561
