We use it because we have to.
When we transitionned to @nogc, only part of the code had the 
@nogc attribute, so how could we done that with just a switch.
When we make a @ngoc library, we can currently add a GC-using 
function to throw in case the no- at nogc people want to use the 
library...
And what happened of the promise to not break things.
I don't understand the complaints at all.
