If I had £1 for every email I've seen in the last decade about platform-related or license-related problems with readline and now editline, I'd be rich man. Super rich.
Could we reduce GHC's surface area by just using haskeline and dumping readline/editline support altogether? Yes that might reduce functionality slightly -- readline/editline are complicated for good reasons. But it's increase functionality in other ways (as Judah says), and by giving us one piece of software that we understand, and can distribute with GHC, it might remove a whole class of problems.
