I don't think it affects how overloading works. You just treat it as a by-value argument as far as overloading and lifetime handling is concerned. In terms of ABI however, you pass the argument by reference.

What is the amount we need to pay to not get another attribute?
This probably wouldn't be a language attribute like @nogc or @trusted. It would be a simple UDA that is defined as a compiler intrinsic. It would likely be defined either at core.attribute, or somewhere at core.internal.
And in any case it wouldn't be anything the D programmer has to deal with. It'd be used to define DRuntime functions, and maybe some low-level Phobos / utility library functions. But not at application code, nor even at normal library code.
