That space in regexp i-search matches all whitespace is not a new feature. We have only changed the way it is implemented, to make quoting spaces more reliable. So I see no urgent need to change this. But I would not mind adding an option to make SPC echo as some other string in regexp i-search. Then, after the release, we could ask users to try turning it on and say whether they like it.
