It looks like `StratifiedRandomSub` was added at some point, but I can’t find it:

There is a `StratifiedKfold` and `StratifiedRandomSub`: [Cross Validation — MLBase 0.4.0 documentation](https://mlbasejl.readthedocs.io/en/latest/crossval.html).

MLJ.jl also has stratified sampling: [MLJBase.jl/resampling.jl at dev · JuliaAI/MLJBase.jl · GitHub](https://github.com/JuliaAI/MLJBase.jl/blob/dev/src/resampling.jl)
