I don't think that changing it to do a implicit isset really fixes the
reason developers use it as previously mentioned. My code is littered
with isset checks, I would rather see a syntax or operator
specifically for this purpose, like ?? since ?: has already been
implemented in a different (and in my opinion in all to many cases not
a useful) way. Syntax doesn't matter to me though long as it serves my
purpose.

  $var = Array('foo' => 'I am set');
  $value = $var['foo'] ?? 'Foo was not set'; // value = "I am set"
  $value = $var['bar'] ?? 'Bar was not set'; // value ="Bar was not
set"; !!no warning!!
