well, this is what's insane about Rails these days. we have a value which is correct in 99.99% of the cases, and we are (at best) debating whether or not to make it the default.
I say at best because obviously in my case I did not see a whole lot of debate. the GitHub issue for it is likewise extremely not-discussion-y. wherever the discussion for this incredibly controversial idea is taking place, I haven't seen it.
