I understand your point, but the situation was already pretty nasty as 
zope.testbrowser already depended on:

    zope.app.testing >= 3.8

I agree that any extra dependency is not welcome, but this feature opens
up a path to radically reducing the dependencies of zope.testbrowser.
See below.

There is also another route open now with the addition of the webtest
feature. We could invert the zope.testbrowser -> zope.app.testing

This is a major re-factoring, but will leave the zope.testbrowser
dependencies looking like this:

    install_requires = [
    extras_require = {
        'test': [

Basically this would require:

    * Re-writing the zope.testbrowser.ftests test application as a pure
      WSGI app (using WebOb)
    * Test only against zope.testbrowser.wsgi and refactor tests to not
      use features from zope.app.testing.functional
    * Move zope.testbrowser.testing into zope.testbrowser.wsgi and
    * Leave backwards compatibility imports in place in

I'd be willing to have a look at this if Benji were OK in principle on
this and someone was willing to review it.
