Thanks for the link to the RFC :)

Excuse me, but I'll be little hard in this post. This for insult the 
community but I want the community really think about the decision it 
made and the reason why.  

I also read why it have been refused here : 
http://www.php.net/~derick/meeting-notes.html#ifsetor-as-replacement-for-
foo-isset-foo-foo-something-else

Is it serious ? 

«
The name for this new operator is heavily disputed and we could not agree 
on a decent name for it.
»

Tomorrow I will not send food to the association for children who are 
hungry because I can not choose between offering Thai or basmati rice.

Stop sarcasm, seriously, this is not an honorable response from people 
making decisions. Take your responsibility and make a vote or impose a 
name, just do it. 

« 
  Instead of implementing ifsetor() we remove the 
  requirement for the "middle" parameter to the ?: operator. 
»

That's not people wants and that's not do their need.
So that not a correct answer of the php developper demand.

« 
  In combination with the new input_filter extension 
  you then reach the original goal of setting a default 
  value to a non-set input variable with:

  $blahblah = input_filter_get(GET, 'foo', FL_INT) ?: 42;
»

I don't see how do that with the actual filter extension. Even if it is 
possible, this is not a pretty short and easier solution than :

$var = (isset($var)) ? $var : 'default';

Why not add a simple new operator who do the job, this is not needing a 
name :

// set a default value if $var is not set
$var ?= 'default';

// equalivalent to :
$var = (isset($var)) ? $var : 'default';
