I think for most of us mere mortals, the only normal use for =delete is making a class non-copyable. And for that, my muscle memory is already wired to inheriting from boost::noncopyable anyway.
private : myclass(const &myclass )=delete;
Just to be safe :-)
Edit: NVM, looks like all major compilers will say that the copy ctor is deleted. https://godbolt.org/z/jTd3714Tb
Foo() = delete;
Foo(const Foo& orig) = delete;
Foo(Foo&& orig) = delete;
Foo operator=(const Foo &other) = delete;
Foo operator=(Foo &&other) = delete;
