The point is "doing better" is pointless unless it serves a specific business value. Beauty is not a sufficient reason to refactor a code base in production - because refactor always has risks, and those risks should be offset always by some tangible expected reward.

Definitely. "Is it good enough for the business?". If yes, then leave it alone. Try to add new features in a safe way with automated tests.

I once worked a contract where it was expressly forbidden by the dev manager to refactor any code unless it was demonstrably necessary to support a new feature. Not much fun for devs at times but I respect the reasons behind the decision (esp. as it was a derivatives trading platfom and it can get pretty expensive pretty quickly when they go wrong).
