Yes, as noted in my 1st paragraph...I'm looking to circumnavigate
this hard-coding. :-/

The catch is that (AFAICT) context processors only handle
adding/merging content to the current context. This would be the
for processor in get_standard_processors() + processors:
self.update(processor(request))
in the django/template/context.py definition of a RequestContext
object.
My subclassed RequestContext object plans to intercept the
Context.__getitem__ call (wherein redaction will hopefully happen
in my custom subclass), and thus needs to be the actual object,
not just a dict-like object merged into the existing
RequestContext object.
My guess would be a patch that changes the
c = RequestContext(...)
lines to be something like
try:
rc = settings.REQUEST_CONTEXT_OBJECT
except:
rc = RequestContext
c = rc(...)
so I could have something like
REQUEST_CONTEXT_OBJECT = MyRequestObject
in my settings.py file.
Unfortunately, I have two major hurdles:
1) it's a rare request -- the standard RequestContext with the
ability to merge in entries via context-processors, likely
suffices for 99.9% of Django users. Very few users have cause to
want to intercept other methods of a Context object.
2) we're staring down the gun at the 1.0 release and doing such
changes will likely (and probably "rightly") be dismissed by the
core developers as a "put it in a post-1.0 ticket and we'll think
about it when we're less frenetic" reply.
Fortunately, I have the source, and am not overly daunted by
patching my local version (as subversion/mercurial are pretty
good about keeping my local changes and still updating from a
remote source) of Django.

It was a good solution to the wrong problem :)
Thanks though,
