I agree that it forces us to be more disciplined to separate them into two processes and clearly define the way they communicate with each other.

The "more naive and stupid way to run them as subprocesses, just like we do for cURL based transport" was primarily because I thought it would be easier to get right (as the transport API and interface has long been established) than hunting down all the callers of die() and touch all the functions involved in the callchain. I won't complain or block if a harder-but-more-correct approach is taken ;-)
