Gah, that's what I *meant* to write. Unfortunately, I put the extra
word in there without noticing, rendering the entire message
thoroughly confusing.

To be clear:

* "build system configuration": telling other tools what's needed to
invoke the build system
* "build configuration": actually telling the build system what it needs to do

The build system config is the part the PEP proposes to start moving
to pyproject.toml (with support for non-setup.py based invocation
deferred to a later PEP).

The build config itself will remain in tool dependent locations (e.g.
setup.py, setup.cfg, flit.ini). If any build config were to move to
pyproject.toml, it would be via the [tool.<name>] mechanism, and be a
decision for the developers of the build tool concerned, rather than
needing to be the topic of a PEP.

Cheers,
Nick.
