Just to be clear, that's exactly what I tried to do in the above
patches. E.g. in 0003 I tried to follow the scheme you just
outlined. There's a part of that patch that addresses pg_dump, but most
of the rest is just parallelism related pieces that ended up using
master, even though leader is the more widely used term. I assume you
were just saying that the above use of different terms is actually
helpful:

With which I wholeheartedly agree.
