"PEP numbers never change" verbiage is not in PEP 1

[AndreasChristianson]

Problem

The introduction to PEP 0 references PEP 1 as a source for

PEP numbers are assigned by the PEP editors, and once assigned are never changed [1].

But PEP 1 doesn't say anything about PEP numbers never changing.

Research

While skimming PEP 1, I found information about the PEP editor assigning a number:

Once the PEP is ready for the repository, a PEP editor will:
Assign a PEP number (almost always just the next available number, but sometimes it's a special/joke number, like 666 or 3141). (Clarification: For Python 3, numbers in the 3000s were used for Py3k-specific proposals. But now that all new features go into Python 3 only, the process is back to using numbers in the 100s again. Remember that numbers below 100 are meta-PEPs.)

and

The PEP editors are individuals responsible for managing the administrative and editorial aspects of the PEP workflow (e.g. assigning PEP numbers and changing their status). See PEP Editor Responsibilities & Workflow for details.

But I didn't find any reference to that number never changing.

Proposal:

Can we change PEP 0's introduction so that the reference is specific to assigning numbers?

PEP numbers are assigned by the PEP editors[1], and once assigned are never changed.
