Doing things I don't understand myself is also a recipe for disaster, and in my experience a rather greater one. The platform team is liable to make mistakes like scaling the service wrong or failing to anticipate upcoming changes. These incidents can be easily resolved by improving monitoring and communication, which are fundamentally useful things that I should already be doing for myriad other reasons. The mistakes I'm likely to make are things like "sequenced a complicated change wrong and null-routed the entire application" or "typo'd a volume name and found out that that autodeletes the entire database including backups", which I am simply not good at avoiding and constitute one of the major reasons I am in engineering instead of ops or IT. We are better off if I do the things I am best at and they do the things they are best at.
