Hi @dcherian and @andersy005, thanks a lot for this PR and for flox. I'm currently trying this with our climate indices library (xclim) and it works well! I get a clear improvement in performance,

In xclim's indicators, all groupby operations are time resampling ops and the best performance is achieved with method='blockwise', by far. Is there a plan to let users control the default method through something like xr.set_options ?

Like, use_flox could accept False, True or any method name? (The default still being map-reduce) ? What do you think?
