There are three issues: first, we need to RESERVE the types for standardization by Guido and crew.

You're just pushing the decision off to someone else. Regardless of who makes it, decisions involving the built-in types are going to make some group unhappy. This list saw several discussions related to standard interpretations for the built-in types back in May and June; here's a selection for you to catch up on:

One particularly divisive issue is whether tuples should be treated as fixed- or arbitrary-length containers. Concretely, does "tuple(Number)" match only 1-tuples with a single Number element, or does it match all tuples that have only Number elements?

Regardless of which you pick, somebody's going to be pissed.

Second, we can decide to do the standardization at any point.

Um, "at any point"? You mean it's conceivable that this standardisation could come after Python ships with function annotations?
