But you know without understanding of any context, that it's the 6th

about the value? You can't be sure that it's a string with length 1,
it also could be another array, an object, a string with length 4711...
That increases complexity and decreases readability.
Your argument falls apart there. Try it:
$a = array("ab","cd","ef");
echo $a{2};
Guess what that prints? {} has nothing to do with strings. They are
100% equivalent to [] and as such add nothing to clarity.
OK, but by dropping {} for strings you also remove the possibility to
have a convention like "[] for arrays and {} for strings".
If I could decide I would drop {} for arrays and [] for strings, but I
fear I will not be asked to decide... ;-)
