We got rid of the mastered for iTunes being separate release a few years ago actually. I don’t think anyone is keeping those separate that I’ve seen. So, if you still run across them, merge them. I do. And haven’t been voted down on one in years. I still keep the hi-res separate, but I’d like to see attributes on links so we can stop keeping them separate, as stated before. Thanks for the comparison on the sample rates. I never knew that some “hi-res” releases are actually blown up from lower rates sometimes.
