Is it really an issue? When you develop an application, the
performance of the application shouldn't be an issue no? From my point
of view, it's the purpose of the opt-in developer mode: enable
"expensive" checks at runtime. But you are right that the cost of the
checks should be evaluated.

About asyncio debug mode, if it's too expensive to be used to develop
an application, maybe there is an issue with additional checks? Should
we remove some of them to be able to use asyncio debug mode in more
cases?
