Yep. The "leftCombining" part is simply adapting a BiBlock to a BiFunction:

Deja vu from last week with CompletableFuture where I ended up supporting multiple distinct forms.

Doing which depends on your audience's tolerance for inescapable goopy adapters vs adding multiple versions of a method that avoid the need for them. For j.u.c audience it wasn't a hard decision, and people told me that the resulting API is a little more user-friendly/decodable anyway.
