In addition to what's said for n+k patterns, I | suggest the standard explicitly encourage (but not oblige) | conforming compilers to issue warnings when deprecated | features are used.
The Revised Haskell 98 report is suppposed to be in conclusion mode. An attempt to decide what features are deprecated would open up a big new debate. One could instead list features which are controversial --- that would be easier. Whether it would actually be worth the work of getting consensus on such a list is not clear to me.
