It's an argument against global knobs in general, regardless of the
method.  In this case, if I read the code correctly, you're saying by
setting that variable that for the entire Zope instance in question, STX
headers should start at the level specified.  I'm not really clear why
I'd want to set that globally, regardless of whether in the OS
environment or in some global Zope thing.
