Gee, I would really love something like Python's enumerate() and zip() (but yes, I know that there's alternatives available that are not in the standard library).

Yes, this is a good addition.

... but I still have to use verbose warts like std::iota in order to make a collection of integers?

EDIT: no, apparently not. Sanity prevails! (see [1]):

    for (int i : std::views::iota{1, 10})
        std::cout << i << ' ';
