Comment:

 Before those fixes, you could literally change the -cq value from 30 to
 10, and not get any difference in file size and quality, because the
 default bitrate capped it down to a quality even worse than 30.

 So that behavior clearly was broken and did not work in any useful
 fashion.
 Instead of experimenting with maxrate, you should experiment with the cq
 value itself, which now correctly works as intended.
 Obviously, if you have a strict maxrate requirement, you can set that. But
 if you want vbr with a target quality in mind, there is no need for a
 maxrate.
