This is an attempt to apply https://llvm.org/docs/CodingStandards.html#use-namespace-qualifiers-to-implement-previously-declared-functions to variables as well. I have another PR for the coding standard change (not yet approved).

Also, the idea that there is just one declaration in a header shared by all who access that variables.
