Because you would immediately loose a bunch of contributors.

For me, anything that adds code to the file structure is clutter. Period.

I know there will be frequent failures. This is unavoidable. Take this
scenario. I often work on SchoolTool. When working on SchoolTool, I am also
working with a writable Zope 3 trunk checkout. I now find a bug in Zope 3
(which I frequently do). I fix the bug in Zope 3, write a test, test the fix
with SchoolTool and I am ready to check in. If I now get a failure in Zope 3
due to Five (which I do not know and do not want to learn), I rather work
around the bug, instead of checking in a fix, since that is less overhead.
One contribution lost.
* One very substantial risk is the understanding of Zope 3 newcomers. I just
sprinted with/mentored Paul Cardune (main developer of CanDo) this week and
he tries diligently to learn Zope 3. They are also using the Zope 3 trunk, so
they can immediately profit from the new features and make transitions
easier. If the trunk becomes even larger, then the chance for Paul to see
what fits together how becomes even larger.
* We have been constantly trying to make the trunk smaller, and suddenly we
blow it up? This does not fit. In fact, I would claim that zwiki and
bugtracker should now be moved out of the trunk and placed into top-level
dirs themselves. They should be tested using the buildbot.
* I have a fear that people will be motivated to make Zope 3 changes to make
them work better with Zope 2, inserting special code just for Zope 2. That
would be about the worst case scenario I could imagine. Right now it is much
easier to oversee the quality of Zope 3 and monitor the checkins. Once a
merge happens, the control will get lost. I just do not have time to read
Zope 2 checkins.
I could come up with more, but I am too tired to think.
