IOW, it wasn't done for some reason that is still unknown ;-).

Thanks.  IIRC, the multi-delimiter capability was used only in one
unit test or test helper that wanted to split at any whitespace.  As
it did not look so important, I could have unified them in the other
direction to only support a single delimiter (i.e. reverting that
commit you found), but I think the end result of this series would
give us more ergonomic API that we can apply at more places than
before, so I am happy I didn't.
