I think encoderer was referring to https://github.com/mozilla/addons-linter/issues/1000#issueco..., where the engineer asks, "Is there any possible way for us to get around this ban?"
Why no "woah, our other angular apps could be affected, is there any safe subset of angular 1?"
There aren't many products where security matters THAT much. I'd hope that the people working on password managers have a total security first mindset.
If you had done in this case, it would have immediately cleared up encoderer's questions about your Github comment.
