If its an absolute no-no that warnings be raised then blanket
suppress them. The snippet of code from the warnings module
should do the job.

I think this whole discussion is pointless bikeshedding. My
point here is that changing the way python is invoked doesn't
strike me as really solving the problem. If you believe that the
warnings are the problem, then lobby to have them taken out.
If you think the timeline for them is the problem, then change
that. If you just want to stop your users from seeing those
warnings, but think they're appropriate, then the tools to do
that already exist, and I would much prefer that you used
