I would argue that Symfony is well engineered, not over engineered. The fact that Laravel is already at version 5 demonstrates just how poorly engineered it was in the first place.
I don't think there have been as many breaking changes in Rails vs Laravel, and Rails at v4 has been over ... 9-10 years? Laravel is < 6 years old, with, from what it seems to be, rather significant philosophical changes between major versions. Doesn't mean it's bad, but perhaps closer to using gentoo vs centos.
