Really? AFAIK we redisplay at the end of every command executed.
We additionally redisplay after processing filters and after receiving
an event that turned out to be a prefix key, etc...
So, AFAICT we generally redisplay at least as often as we run
post-command-hook. The only case where we don't is when we can't keep
up with the input events in which case we skip redisplay, but that's the
case where we're *already* too slow.

It was developed because people like Alan are so bothered by the
flashing that they're going through lengths to find other ways to
avoid it.

It shouldn't slow down cursor motion, normally (at least not in any
measurable way).
Also I expect the implementation will change over time, as experience is
gained with it.

Code like:
var x = "foo y = "bar";
where the user is in the middle of writing `x = "foobar";` but hasn't yet
closed the string.
