> Developers don't want to ever be paged because they don't want to be bothered

This is a very reductive statement.

Developers have experienced their best colleagues burning out and leaving jobs because of on-call being completely overwhelming.

Developers want to behave intelligently.

Developers want the system to work.

Developers don’t want to burn their lifespan for false alarms that are being sent because someone didn’t spend 30 seconds thinking about whether a human being needs to be woken up in the middle of the night for whatever widget they’re slapping together.
