It's easier to justify in a fast-moving greenfield code base with a verbose language... but I won't defend it. I've gotten better and I'm still getting better at breaking these things up.

I brought the 10-12kLOC PR up as an example supporting my point of view. I don't encourage the behaviour. Most of my PRs these days fall under the 1500LoC mark, tops -- maybe a bit more if it's a tricky component that needs a ton of tests.
