Hmmm strange, because for "pytest.config" to be available, it means the
user is running the "pytest" command. You can see here how pytest used to
do it:
https://github.com/pytest-dev/pytest/blob/d3549df5b94137453b832345a9b8074f518731b0/src/_pytest/main.py#L191-L192
(It is inserting a wrapper object to issue a warning, but other than that
the mechanism is there)
So in theory your plugin is running under pytest, otherwise `pytest.config`
would raise an AttributeError.

We don't have any plans to deprecate `metafunc.config`, as doing so would
break *tons* of code, and is really part of the API and no great downsides
(as opposed to the pytest.config which was a nasty global).
If you can't make the "pytest_configure" suggestion work, this seems OK to
me.
