UI is the hardest and most time consuming thing to implement, and this kind of feature sounds like it needs special dedicated UI, where you go through a giant list of all your global variables and enable/disable them or something. Considering there's what seems to be a pretty easy workaround, I'd rather not do difficult implementation work for something this minor. Our time is probably better spent on things people want more.
We've announced several hires on our blog now, by the way.
