You may feel it's very small delay, but if you batch edit your songs often (which I do) it's actually pretty noticeable. Try to select 10 tracks and update the album name and feel the difference. Most of time wasted on remuxing the file comes from re-writing the whole thing on your hard disk, which is more noticable if you save your songs on HDD. Is it really that bad? No. But it's nice to have some padding. Same goes to MP3s and especially FLACs (which is even more noticeable because file size is much larger). Some of the digital distributors for hi-res (hi resolution) music do use "flatten" files, and it's quite annoying to edit them.
