Yes and yes. Same as Martin Aspeli's reasons: testing on multiple plone 

I think the main thing is to be sure that the installation doesn't add any 
zope specific folders to PythonPath in the registry. The Plone installation 
for example adds (or added) some folders to PythonPath which meant that 
multiple plones using the same major python version would try to share 
parts of the Plone installation. Not adding folders to the pythonpath 
registry key allows coexistence, and there are more than enough ways to add 
folders to pythonpath without using the registry.
