Depends on how one approaches it.
I wasn't thinking of a major redesign when I said that.
If one wants to classify *any* change to the ui-file API as major, go for it,
but to me some changes are easier than others.
[It's not clear to me yet that any change will be necessary, btw.]

Note that while we do explicitly call *_unfiltered with single characters,
unfiltered output is not in itself broken up into single characters.
