You can also get really creative with frameworks, specially if you need to quickly overcome some strange limitations imposed by framework. There is also a long term risk with using frameworks - somebody here mentioned method renames in Laravel, that makes upgrading difficult.

Im not talking about writing your own http server, or building the whole database access library. You can use some ready made libraries. As long as you keep proper boundaries between IO and business logic, you can fairly easy change the IO libraries.

Of course there is quite some overhead there, and for some projects it makes not sense.
