One example is users stuck on e.g. Zope 2.10 or Plone 3.3 (or even
earlier). They cannot upgrade because they are using customized
installations and don't have the knowledge or resources to upgrade
the systems to later versions.

Building your own Python installation often isn't a possibility
in corporate setups, e.g. because they are only allowed to run
software for which they have support contracts.
