I think that what it comes down to is that because of the whole auto-decoding
fiasco, when Andrei originally did the work on output ranges, he made it so
that char[] and wchar[] were not output ranges for all of the reasons that they
weren't input ranges. However, with the improvements to put over the years, it
becomes increasingly silly for it to not work. And if we can make the changes
for output ranges without breaking any existing code, then we definitely
should.
