Would not have been an issue if we were using std::function, though.

Then again, it might have been an issue if we *were* using std::function from 
a C++ standard library that did not update to noexcept with a C++ compiler 
that did (such as when using Clang on Linux with libstdc++). Since this error 
would have shown up in the user's code, we would have washed our hands and 
told the user "upgrade your C++ standard library, downgrade your compiler or 
stop using C++17".
