Why setuptools = 7.0?

[fulv]

Why is this line still in the buildout.cfg.j2 template?

setuptools = 7.0

Even for Plone 4.3.20, I need to override it in my local-configure.yml if I want to have any hope of buildout succeeding.

https://dist.plone.org/release/4.3.20/versions.cfg

setuptools = 26.1.1

I don't know where this requirement for 7.0 came from, but the most recent jump to 20.x I could find was between Plone 4.3.7 and 4.3.8:

https://dist.plone.org/release/4.3.7/versions.cfg:

setuptools = 0.6c11

https://dist.plone.org/release/4.3.8/versions.cfg

setuptools = 20.1.1

Also:
https://dist.plone.org/release/5.0b3/versions.cfg

setuptools = 5.8

https://dist.plone.org/release/5.0b4/versions.cfg

setuptools = 18.0.1

But which version of Plone has ever needed 7.0?
