Wave/Z should never error out

Consider the following snippet

      Wave/Z/SDFR=$"root:I_dont_exist" data

This currently errors out with a user function error as the data folder could not be found.
In my eyes it would be nice if the /Z flag would also ignore non existing datafolders given with /SDFR.

I know that I can use

Function doTest()

    try
        Wave/SDFR=$"root:I_dont_exist" data; AbortOnRTE
    catch
        print GetRTError(1)
    endtry
End

but thats much less convenient than /Z.
