I recently read on their blog that they are trying to put a lot of effort into making HHVM compatible with widely used frameworks. So it seems that there is an effort in making it run good for everyone than just for FB. Nevertheless we all agree that HHVM and php-src are separate projects with different goals at the moment. However the community would benefit from a formal language standard. I am not sure how python does it but they have a healthy community of language reimplementations (pypy, jython, etc) and I think the PHP community can learn from that and help people choosing which runtime fits best for their needs.
