In certain assumptions dask isn't needed for concatenation. One case is when a.var_names == b.var_names, i.e., when adatas align for a concat_aligned function. In the codes of researchers in most cases a.var_names == b.var_names hold when there is a concatenation. So it might be worth the speedup but we will first need to investigate how it would perform.
