Note for the internal reviewer: This class has some OSS usages, so removing mBackingMap hungarian notation would break OSS, probably that has to be suppressed if the linter fails

This is the GH search

But, I may be misinforming by saying that mBackingMap is used (I could not find direct references for that in some of the initial results), but given how many libs use the class, I'd still go on the safe path

@mateoguzmana given the last GH search, I think we can actually rename the field and make it internal/private
