Review Comment:
It seems we have two different styles for const placement: `const
std::shared_ptr<Type>&` vs `std::shared_ptr<Type> const&`. Do we want to stick
to one style?
You don’t need to make changes in this PR; I’m just curious if this is
something we should pay attention to. @wgtmac @lidavidm WDYT
