Yes, I don't think most users are going to notice this either way - the
overwhelming majority of them won't have noticed a problem and won't
notice the fix going in.  It's then a question of if the people who saw
the issue and cared did the userspace compenstation or not, my concern
is that more will have done than won't given that it's a fairly common
thing to have control for given that you also often get delays added in
things like surround sound systems which aren't visible to the playback
device.
