Hi @brando90 and thanks for this PR,

Unfortunately I think this change goes against the the design principle that get_tasksets should reproduce benchmarks from the literature. My recommendation is to include the augmentations in the benchmarks themselves (like you already did in #303 and #305 -- thanks for that!).
