should ScopedPtrMap be in namespace base::, same as ScopedPtrHashMap? Maybe good
for a follow-up..

I've asked Dana this on http://crbug.com/502128. If we're going to change it, I
want to do it *before* this CL because otherwise there will be a lot of churn.

Done in precursor CL https://codereview.chromium.org/1194373002.
