As a counterpoint I'm working on an ex-PHP4 codebase, that's been "developed" (in the loosest possible meaning) by assorted people over 15 years. It's full of security vulnerabilities and the worst code I've seen in my career. I'm also working on a modern Symfony PHP codebase using popular 3rd party Symfony bundles. I've used Symfony for a decade but find the compiler passes and levels of abstractions (particularly when debugging 3rd party bundles) slow me down and make the code less understandable. Yesterday I spent half a day tracking down a bug which was the wrong setting in the config, but was obscured by too many layers of indirection. I'd take the terrible but understandable codebase any day as I know I can debug and improve it more easily.
