Unless I'm missing some subtleties, that appears to just be a more
confusing version of string concatenation.

$string[] = 'a';

is equivalent to :

$string .= 'a';

Is that correct?

It seems unnecessary. Unless I've misunderstood what it does, it's
just a complete duplication of functionality we already have (, in a
way that is likely to confuse people, imo) and having duplicate
functionality is not so good.

At the very least it needs to be part of a separate vote option - but
my opinion is that it's not needed at all, and should be left out
entirely.
