Not sure either; it will clearly depend on actual uses.
This said, if the main case where the quote would be needed is when KEY
is a (non-keyword) symbol, then it's probably worth the extra
flexibility since you could say that an element of the form SYMBOL is
treated as equivalent to ('SYMBOL SYMBOL), so the extra quote will be
very rarely needed.
