You haven't just spent several tortuous weeks trying to figure out how on
earth to correctly prompt for cookies in a multiprocess browser in a way
that doesn't break synchronicity requirements the way we have.

Synchronous access to state didn't cause many issues when browsers were all
single-process, single-thread.  That is increasingly not going to be the
world we live in.  As Jonas mentioned, just look at localStorage (which,
contra your position, many developers have proposed using very much like
cookies) for recent history of why synchronous APIs are troublesome.
