Well, maybe dumb is too strong a word but these types of edge case
interfaces tend to cause subtle issues over time while being
marginally useful at best. Sure it helps a couple odd users to write
slightly less code, but that's such a marginal gain compared to the
fragility it adds by being another one-off thing. So, yeah, it's a
silly thing to include in an interface as widely use as workqueue and
it's more of a historical remanant than anything else at this point.

Thanks.
