I think you need to clarify what you mean here.

I'd like you to provide a step by step analysis of what happens and
what the effect of your proposed change is on AIX *AND* what it might
mean for other X11 platforms, as I don't have time to reverse engineer the
reasons for the odd-looking change.
It looks like a hack to short-circuit support your syntax.
Right now I am saying no to this.
