Hello all,

How is the status of switching from deprecated distutils to pep517 build?
I remember some time ago to see some changes but it seems to stalled now.

Not stalled. Not every Python package in the wild has flipped to PEP-517 yet.

For people upgrading to pep517, are depends correct?

BUILD_DEPENDS= \
${PY_SETUPTOOLS} \
${PYTHON_PKGNAMEPREFIX}wheel>0:devel/py-wheel@${PY_FLAVOR}

Or ${PY_SETUPTOOLS} should be replaced with ?
${PYTHON_PKGNAMEPREFIX}setuptools>0:devel/py-setuptools@${PY_FLAVOR}

The latter. Originally I implemented ${PY_SETUPTOOLS} when devel/py-setuptools58 was still viable for the remaining USE_PYTHON=distutils cases, but both significant changes in later devel/py-pyproject-hooks breaking setuptools 58 (and rendering maintenance uneconomical) and continued maintenance of setup() direct execution obviated that plan. Until I update devel/py-setuptools itself, which will specify devel/py-wheel as both {BUILD,RUN}_DEPENDS, you will need to also specify the latter in each setuptools PEP-517 consumer.

I will update the documentation (mostly the wiki?) accordingly.
