As I can basically access and modify anything from an external method
(thanks to Python power), you must either define very clearly what 
I'm allowed to do, or decline any assurance that it will work in any 
future release. 

Of course I have some (hopefully good) idea about what I can do from
an external method without breaking things in the future, but since 
this is not a compiled (aka, locked & sealed) environment, I think you
have to exclude it. This applies to external methods and writing of 
products, but not to TTW use of Zope's facilities (including scripts).

Even if I test and report it, you may rightly say that I shouldn't 
have "touched" that part in the first place.
