[Zope3-dev] zcml in config db?

I'm new here.. almost certainly these comments are off-base. then again,
sometimes an idea "from outside" can be helpful. So here's a crazy
thought before I go to bed..
I wonder if the configuration done by zcml might not be better if it
resided inside a ZODB, and was manipulable at runtime, and more
importantly separate from the source code.
It couldn't be the normal "instance" zodb, but rather sort of like a
"classinfo" zodb that took care of all the linkage info. Of course, the
system would have to be made a bit more robust so it stays up when
modules w/ syntax errors are loaded, for example.
The biggest reason: I can imagine that when deploying a package, various
configurations, for instance security, but also adding
internationalization, have to be adapted for the specific site. This
way, they could be deployed without access/change to the source tree
(after it has been "plunked down" in the python path), and further
customization could be done, if necessary, remotely. Also, sites that
"have to stay up" could be reconfigurable on the fly (though one would
have to be careful about disabling the core system!).
Also, those pythonistas who object to zcml not being in python will have
less to see when they complain. This at least drives home the point that
this config isn't logically part of the code. :)
Zcml would stick around as an import/export/diagnostic/backup tool.
