We're talking about different things here. PHP is an universal platform
and PHP 7 would be offered as upgrade to all PHP users - running ZF1,
ZF2, Symphony, Drupal, anything. If there would be a sizeable chance
that their existing code would not run on PHP 7, people would not
upgrade. Our upgrade record is not stellar as it is, even with
extraordinary effort we put in keeping BC 5.4->5.6. If we break major
libraries in 7, I am afraid we'd have adoption problem.

ZF2 wasn't really an upgrade from ZF1 - nobody expected you to just jump
from ZF1 to ZF2 on the same code. So it's not the point here, the point
is that ZF2 is an example of major framework that uses the feature which
this RFC proposes to break. There are more.
