Honestly, there is a lot of praise of the middleware in these projects, but I recently found out that most of them are unable to handle parsing the Accept and Accept-Encoding header properly, that is: according to the RFC, with weights.
This means that the general perception "these projects are production-quality but stdlib isn't" is misleading. If I have to choose web framework or library that implements feature X incorrectly versus one that doesn't have X at all and I have to write it by myself, I will with no doubt choose the latter.
