It was used by rye before rye and uv sort of merged and is used by pipx and hatch and mise (and bazel rules_python) https://x.com/charliermarsh/status/1864042688279908459
My understanding is that the problem is that psf doesnt publish portable python binaries (I dont think they even publish any binaries for linux). Luckily theres some work being done on a pep for similar functionality from an official source but that will likely take several years. Gregory has praised the attempt and made suggestions based on his experience. https://discuss.python.org/t/pep-711-pybi-a-standard-format-...
Apparently he had less spare time for open source and since astral had been helping with a lot of the maitinence work on the project he happily transfered over ownership to themin December

That's not to say they aren't downsides. https://gregoryszorc.com/docs/python-build-standalone/main/q... documents them. As an example I had to add the https://pypi.org/project/gnureadline/ package to a work project that had its own auto completing shell because by default the builds replaces the gnu readline package with lived it/edit line and they're far from a drop in replacement.
