Description
Following the adoption of http://www.open-std.org/jtc1/sc22/wg21/docs/papers/2018/p0634r3.html many uses of ‘typename’ throughout the library are now redundant. They should be eliminated to provide a cleaner modern presentation of the standard library, much as when we switched from typedef to using.
Such a wide-reaching change is likely a policy decision to be approved by LWG, but application is more likely an editorial issue (requiring careful review) to avoid overloading precious LWG time.
Suggest this should be an issue for C++23 to avoid disrupting the imminent progress of C++20, and allowing adequate time for reviews. May consider updating one clause at a time, to ease review load.

Research direction
Start by reviewing the C++ standard library clauses affected by redundant uses of “typename” and the rationale in P0634R3. Work clause by clause, with careful editorial review; done means the redundant uses are removed consistently without disrupting the C++23 draft.
