An anecdote about removing exec().  Back in 2012 I interviewed Kristjan 
Valur Jonsson, then of CCP Games, for my podcast Radio Free Python.  He 
said that due to memory constraints they'd had to remove the compiler 
from the Playstation 3 build of Python for some game project.  This 
meant that namedtuple didn't work, which had knock-on effects for other 
bits of the standard library

So security concerns aren't the only reason for removing the compiler,
