I just read the thread and use Python, I can't comment on the % speedup attributed to uv that comes from this optimization.
If it was a optional toggle it would probably become best practice to activate compilation in dockerfiles.
It seems like tons of people are creating container images with an installer tool and having it do a bunch of installations, rather than creating the image with the relevant Python packages already in place. Hard to understand why.
For that matter, a pre-baked Python install could do much more interesting things to improve import times than just leaving a forest of `.pyc` files in `__pycache__` folders all over the place.
