Is it possible to edit the PEP to reflect the current design decisions?

Specifically:

• Remove: "Because of the new levity for * and ** unpackings, it may be advisable to lift some or all of these restrictions." (in both abstract and specification)
• Extend: "Currently duplicate arguments raise TypeError. This remains true for duplicate arguments provided through multiple keyword argument unpackings, e.g. f(**{'x': 2}, **{'x': 3})
• Add some examples of dictionary overriding to the list of examples:

{'x': 1, **{'x': 2}} {'x': 2}

{**{'x': 2}, 'x': 1} {'x': 1}

• Remove "if the restrictions are kept" (they are)
• Remove "If they are removed completely..."
• In disadvantages, remove "if the current are kept" (they are). Don't write "* unpackings", write "iterable unpackings"
• Remove "if the current restrictions are lifted"
• Remove "Implementation" section (it's done!)
• Add to specification: "f(*x for x in it) and f(**x for x in it)" remain SyntaxErrors.
