I just want to chime in at this point that PEP 402 actually provides rationale to answer a lot of the questions that are coming up in this thread, and which are still valid in a PEP 420 world. While some folks have complained about PEP 402's length, they're mostly people who were already present for all those discussions and hashing out of rationales. ;-) (I actually wrote 402 with the intent of answering as many as possible of these objections in advance, hence the length.) (On a more serious note, it might help to crib some bits of 402's rationale arguments into 420, so that we don't have to keep answering already-dead proposals that keep coming up, like, "why can't you just add a special file named xyz to fix this".)
