Well, you'll be happy to know that C++ pretty much allows that, but not for templates. You can use auto in parameters if the calling context allows inference, for example when writing lambda. Similarly, you can use auto as a return type if the function implementation is immediately given and the compiler with infer the return type. The new starship operator (<=>) typical usage is pretty much declaring it with an auto return type and "= default" implementation.
