Analysis for game meta, what do you think?

Recently there are projects analyzing civilisation balance, win-rate over patches or maps. For example Aoe2Analyticz and Age of Empires 2 Civilisation Performance Statistics
and that is great work to be appreciated for the community.
I am wondering if there exists works studying how the meta has evolved over the patches. Topics like, how often do we see certain strategies these days.
From tournament observation, we see a trend of maa archer over drush archer (and even more over drush-fc). We could expect that after T90 mentioned noboru-rush, the incan play style has changed. The water meta shifted from feudal galley war in AOC days => fire-galley in wololo kindoms => galley war in DE between HC3 and HC4.
I think it would be interesting to see these trends qualitatively through a statistic.
