I doubt that regularly releasing breaking changes that reduce uptime is a good strategy to get a bonus or promotion.
Releasing 1 change a year with a 100% chance of working -- no promotion for 10 years
Releasing 10 changes a year each with a 10% chance of breaking something -- 1 in 3 chance of promotion in a year, and a 2 in 3 chance of downtime
Where did that assumption come from? Also are you claiming that it takes 10x more time to release a non-breaking change?
