Can there even be geodetic drift of the poles? I sort of assumed that our lat/lon system is based on the poles being fixed points as a matter of definition.
Each ellipsoid is rigidly defined (well, some historic ones are sloppy), so WGS84 won't drift .. (that's a bold statement, is it true down to the micron and if so what are the absolute* datums to reference against?).
That said, there are literally hundreds of historic pre WGS84 ellipsoid|datum pairings, each with a somewhat different "survey map pole".
Historically geodectic poles have shifted as a function of datums.
The main point here, such as it is, was to poke at the infomation free aspect of "polar drift" as a comment .. which pole and what does that have to do with climate change? etc.
