if a function's argument is const ref, what would be the problem of allowing it to to be passed const ref lvalues + rvalues?

>  Not to bring back something that might be considered closed, But is auto ref going to be allowed for non-template functions in an upcoming version? There's plenty of times I'd like to use ref when possible but don't want to write a forwarding function converting non-ref to ref.

The pull is still there
(https://github.com/D-Programming-Language/dmd/pull/1019) but as
I'm asking here:

an official statement would be pleasant.

No response probably means "you get no official statement"? ;)
