> Not saying this tradeoff is for everyone, and I've never used C++ professionally so I'm probably ignorant. But are you saying it's common with production projects that use a compiler from 2003 or earlier? What's the use case? Let's start with the fact that newer doesn't mean better. With already deployed compiler you have tested it and know that it works good enough (code it generates, bugs you have workarounds for, etc). Where with new compiler you are on step one. You must do work again. Or vendors just support particular version they have patched. Or you are scared of GPL3.
