> It's something that we in the Python community have already learned due to the historical unreliability of our equivalent package repo, PyPI.
learned sounds a touch condescending to me for some reason. The python community has certainly run into it, but (anecdote time) in my experience people still often rely on pypi for their deploys (but use the --mirrors option to pip).
Encountered may be more appropriate.
True, "learned" does sort of imply that it's a best practice now used by nearly everyone in the community. I know that's far from the truth. "Encountered" is more appropriate, so I'll edit my OP.
