Because it makes no sense to put the cart before the horse and ask:
what does Forth need?

MT and RT requirements are primarily determined by the hardware and
the response time requirements. Just as an example: for a time-slicing
system with fixed cycles in a PLC, the software requirements are
different than for a desktop Forth running on Linux. Standardization
makes little sense here. And there are also hybrids: interrupts for
Task0 (scheduler) that controls cooperative subtasks 1..N, but can
also interrupt them preemptively eg. on detected cycle overload.
