By saying that "these are things that will not change", then you _are_ 
sort of banning talk about them (if, as you assert, "such talk isn't 
going to actually result in any changes to the language" then you are 
saying don't waste your breath, we won't even consider your arguments).

I think I get Sven's point. A long time ago, someone probably said 
"Python will never have any sort of type declarations.". But now there 
is type hinting. It's not the same thing, I know, but such a declaration 
in a PEP might have prevented people from even spending time considering 
hinting.

Instead, if the PEP collected - for each 'frequently' suggested change - 
a summary of the reasons WHY each aspect is designed the way it is (with 
links to archived discussions or whatever) then that IMO that would be a 
good resource to cite in a canned response to such suggestions.

It's not that "these things will never change", it's more of a "you need 
to provide a solid argument why your suggestion is different to, and 
better than, the cited suggestions that have already been rejected".

Probably a lot of work to gather all the references though. But it could 
start out with one or two and grow from there. Add to it as and when 
people bring up the same old stuff next time.
