When you're Oncall you aren't Oncall 24/7 forever. It usually rotates amongst the engineers in the team. I'm on a team with about 10 engineers in it so you're on call about a week every two months. I call that manageable.

Engineers should 100% be responsible for owning their code, and fixing any issues that arises from it. After all they're the ones that wrote it, aren't they the best people to fix it when it breaks?
