Is it broken that this is true?:

$ touch src/python/pants/__init__.py
$ echo "/src/python/pants/__init__.py" >> .gitignore
$ ./pants package src/python/pants:pants-packaged
09:12:27.18 [INFO] Initializing scheduler...
09:12:27.40 [INFO] Scheduler initialized.

$ zipinfo dist/pantsbuild.pants-2.11.0.dev1-cp37-cp37m-linux_x86_64.whl | grep "pants/__init__.py"
-rw-r--r--  2.0 unx        0 b- defN 22-Feb-26 17:12 pants/__init__.py

And, if not, this is surely broken:
