Hi Hartmut,

saving some space and unvendoring components that we also have separate
packages for. (As I understand it, ensurepip, which installs both pip and
setuptools, is merely a convenience tool if you install Python from
source yourself – not for distributions.)

No, try

	git clone https://github.com/pypa/pep517.git
	cd pep517
	pip wheel --use-pep517 -v .

which has no setup.py and uses flit instead. pip can build it, because
it supports PEP 517-based builds. As I said, if we decide to keep it
bundled with our python package, there’s no good reason to choose
pypa-build.

Cheers,
Lars
