Tobias is the main Meson driving force in SageMath. The Meson builds are only done for sagelib, and for some other sagemath Python projects, such as https://github.com/sagemath/cysignals More Python things in https://github.com/sagemath/ need an update of the build system, away from distutils/setuptools "python setup.py"... I don't think we're going to push any meson to upstream projects, in particular certainly not to non-Python ones.
