So my proposal is simple (and not really new): let's revert back to the way things were in 2.6 and earlier, with DeprecationWarning being visible by default

As part of this though, I'd suggest amending the documentation for DeprecationWarning [1] to specifically cover how to turn it off programmatically (`warnings.simplefilter("ignore", DeprecationWarning)`), at the command line (`python -W ignore::DeprecationWarning ...`), and via the environment (`PYTHONWARNINGS=ignore::DeprecationWarning`).
+1 I’d also consider adding convenient shortcuts for each of these. I think DeprecationWarning is special enough to warrant it. Possibly: warnings.silence_deprecations() python -X silence-deprecations PYTHONSILENCEDEPRECATIONS=x Cheers, -Barry
