support for in-process clients ("plugins") is partially present in my
evolving "proposal/codebase". its entirely expected that it will
fully support both kinds of clients.

as mentioned, it also prevents CPU overloads by using a watchdog timer
built into the main audio thread which enforces its own priority being
higher than those of its (out of process) clients.
