   Welp, that's nice! Thanks @jorisvandenbossche . We probably can add that as 
a default configuration on our `pyproject.toml`, using:
   > time python -m pip install -C cmake.build-type=Debug -C build.verbose=true 
--no-deps --no-build-isolation -vv --config-settings=build-dir=build -e .
   
   I got on a rebuild:
   ```
   real 0m11.357s
   user 0m15.001s
   sys  0m1.548s
   ```
   That's indeed an amazing improvement.
   
   I've validated that changing a pxd file or a PyArrow C++ file only compiles 
the required, example:
   ```
   real 0m40.480s
   user 1m54.172s
   sys  0m6.618s
   ```
