That's not  true, the compiler can (and does) warn about legal code.

I'm confirming this, we will want the warning at some point, and it would allow
us to improve this part of the -Weffc++ warnings:

* Item 11: Define a copy constructor and an assignment operator for classes
with dynamically allocated memory.

(see PR 16166 for more details)

Maybe we could call this warning -Wdeprecated-special-members, and have it
enabled -Weffc++ and in C++11 also by -Wdeprecated
