Discussed in Prague as a joint LEWG policy on allocators discussion.

Do not add allocator support without implementation experience.
Unanimous consent.

Reaffirm that we support allocator awareness even for non-allocating types.

Reaffirm that we support pmr for non-template types that may need to store or propagate an allocator. (Prefer pmr over allocator type-erasure.)

Endorse a policy that class templates that are not type-erased have a counterpart basic_ template with the allocator template parameter.
