Yes, I'm thinking that, too. I'm running my system Python with that
set, and it seems to fix my various problems.
For others following along, here's the pointer to the Apple docs:

Yes. My appscript scanning app is working fine with LSBackgroundOnly set,
and no rocket in the dock. I can logout, the various Python processes are
