Comment (by klaussfreire):

 It's not a serious one. It's just that it won't target the bitrate so
 accurately as before, only when using M/S coding (which didn't even work
 before). So you could say it's not a regression, because the case that
 doesn't properly target the bitrate didn't even work before, it's overall
 better.

 I can fix it (and I might post a patch fixing it), but I'm not sure how
 long it will take, so I don't want to delay committing these advances even
 more just for this that isn't even a regression.
