while i understand this 'fixes' things it is misleading. we should just say setuptools is an actual dependency, which it is .

It is not. It has never been, until #41503 accidentally made it so

Of course it was always a "dependency", but there is a difference between "optional" and "required" dependencies. We have lots of optional dependencies that are not declared in install_requires

Apart from the "required dependency or not" discussion (-> let's have that in #41815, since this PR doesn't actually address that), there is also an "import time" reason for merging this PR.

Importing pkg_resources is quite expensive, and doing it at import time of pandas (while it's only needed when plotting with a custom backend) would add something like 20-30% to pandas import time.

Tested with python -X importtime -c "import pandas, pkg_resources" in an environment with released pandas 1.2 (which doesn't import pkg_resources). The results of a single run pasted below: importing pandas takes 393 ms, importing pkg_resouces an additional 91ms, which would give an increase of 23%. Those numbers are quite variable though, but based on repeating it a few times, it was always between 20-30%. 
$ python -X importtime -c "import pandas, pkg_resources"
