Being able to write synchronous code is one of the basic uses for Workers
in the first place.  Synchronously creating streams is useful in the same
way that other synchronous APIs are useful, such as FileReaderSync.

That doesn't necessarily mean having a synchronous API for a complex
interface like this is the ideal approach (there are other ways to do it),
but that's the end goal.

(FYI, the messaging in Workers isn't inherently async; it just happens to
only have an async interface.  There's been discussion about adding a
synchronous interface to messaging.)
