[Grok-dev] zope.app.wsgi adapters not registered by default

I'm upgrading a grok1.1 project to 1.4, and I came across this problem:
I have some views that allow XML export of some objects. The view's render
method returns an on-the-fly generated tempfile.TemporaryFile object. That
used to work before, but not after upgrading to 1.4: I got a rather obscure
'TypeError: The result should be None, a string, or adaptable to IResult.'
After some searching I found that zope.app.wsgi does define adapters for
this, however, they don't seem to be registered by default. Adding
'zope.app.wsgi' to install_requires in setup.py solved the issue.
Was this deliberate, or an oversight?
If it is deliberate, there should be some mention of it in the docs.
I tried with a clean 1.4 project, and had the same problem:
create a new project and add
from tempfile import TemporaryFile
tempfile = TemporaryFile()
browsing to '/test/download' will give you the error (provided the app was
added as 'test' of course).
