I prefer to not give up compression to get larger pages. We might see support for 32kb pages with compression in another variant of MySQL. Benefits from larger pages include 1) fewer seeks for full table scans, 2) more large blob columns stored inline and 3) (maybe) larger index keys. I think #2 can be a big deal for saving space.
