I mean the Java community didn't use it anymore, because the "annotation inside comment" thing is worse than "annotation supported natively by the language". Granted, it's the only practical way to do it in PHP for now, but it still didn't change the fact that it's bad, IMO.
I wonder why SensioLabs (the creator of Symfony and Doctrine) didn't make the PHP's annotation RFC into reality. They are a quite huge powerhouse in the PHP world...
