It’s probably inevitable but a policy requiring strong justification for and regular review of any “aftermarket” changes might slow down or reverse the descent. The closer it is to vanilla the easier it is for (almost) everyone. Managers and workflow czars (nice one btw) of course would be inconvenienced but they should be comfortable making really strong justifications for making the lives of developers harder just to make their reporting smoother.
I attended a talk by a Netflix employee where they talked about a sort of organizational immune system to aggressively prune bureaucracy and policy by forcing it’s existence to be regularly justified. It helped me connect the dots and realize that allowing heavy customization was as much a poison as it was a boon.
