I don't understand this objection. Being able to compile something with no dependencies is different from being able to run something with no dependencies.
I think you're confusing installing the compiled package and using it (which doesn't require anything else) with _compiling_ the package, which requires XCode on MacOS
"q is packaged as a compiled standalone-executable that has no dependencies, not even python itself."
This is not quite true, on MacOS:
"q: A full installation of Xcode.app 12.4 is required to compile this software. Installing just the Command Line Tools is not sufficient.
Xcode can be installed from the App Store. Error: q: An unsatisfied requirement failed this build."
