I think it's more then that

It changes the way you will think about MVC and the way you develop
and take care on separate your model, view controller components.

It's like aquisition in Zope 2, you don't have to take care where
your attributes coming from, they're just there. Doesn't matter
if this is good or bad, it's just a very different concept.

Defently a bad thing is, if to many developer start using
zope.globalrequest in their 3rd party packages. We can't reuse
this 3rd party packages whithout using a global request variable.

In my point of view it's a fundamental change on what an application
is built on. Probably the good thing is, it's easy to provide such
a global request as long as you use a webserver (publisher).

just a sample;
In my point of view an application like a wiki or forum etc.
should get developed as a python application without to require
a global request because it's just a (MVC) model part. There should
never be a request involved. If such a wiki needs a "last modified user"
argument. This should not get set by a global request lookup.
Or at least not the model should use such a global request by itself.
If you need to set such a "last user modified" argument the view/controller
should be responsible for doing so. I'm pretty sure if we have a global
request available we will see very quick that developer start to use
the global request in the model part.

Note, mixin model, view and controller responisibilities into one 
component/object make it allmost impossible to replace or reuse
parts of it.
