I said it's good to discourage bad practices. Unless you think refactoring is a bad practice, you have understood my comment incorrectly.
But also you can remove the part about discouraging from the previous post, if it's confusing:
Minitest enabled bad practices for a pragmatic reason.
The tests were not following bad practices for a pragmatic reason, they did it by mistake.
Enabling is less bad than doing, and minitest had a reason while the bad tests didn't.
Therefore minitest doesn't suck and those tests do suck.
Edit: fixed a couple typos
