But perhaps I was misinterpreting what was said. Of course there is
some delay before a burst-throttle and the engine reaching full power
due to the necessity of accelerating the mass of the moving parts
involved.

I think he's saying that any delay is even shorter in the Merlin, but
even more than that, the power differential in that Merlin between
cruise or whatever and "burst throttle" is magnitudes more than in your
360 or 540. These two things together are maybe what get you into
trouble if you are not careful and power is not increased smoothly.
I have a flight manual for the P-51 that I got when I flew Crazy Horse.
On take-offs and go-arounds it also says to advance the power "smoothly."
