Additional feedback received off-list in response to the python-committers thread:

* the current preamble is still overly legalistic and could stand to be toned down (e.g. finding a friendlier word than "disclose" in a couple of places)

* the page doesn't really explain why it exists. There's hints of that in the "Limitations on Scope" section, but it would likely be better to have a more explicit "Goals of this page" section.

I'll draft an updated version of that and post it here.
