I think this is mostly fine. we will likely need to follow up on the linked to page, since the template<> at the top doesn't quite look right to me. its template <> for the case where its Foo<int, double>, and template <T> for Foo<int, T>.

As a side note, it may be a little annoying to land the rest of the allocator patches if we keep adding core Info handling before the migration finishes. If you have capacity, more reviews on that stack would help speed things along, and reduce integration cost for me 😄
