Or perhaps it could be an optional dependency in the mean-time? Since 
we're only talking tests, here, it's not terrible of developers have a 
bit more choice over dependencies. For example, zope.testbrowser itself 
requires Five 1.4 to run on Zope 2. Plone runs testbrowser tests if 
they're available, and prints a warning if they are not.
