In my experience having a formal platform structure helps tremendously to roll new solutions. When the platform officially provides something, everybody in the company can make use of it right away. Unlike the pet project that's being pushed by a random manager.

Breakthrough can be pushed by rolling a second library/framework/platform. Like AWS ELB and ALB. Then developers can adopt the later if it's so much greater, but they won't because it's 90% of the same and who wants to work on migrations?

Large organizations are fundamentally split apart. First part of the org wants A and B. Second part wants B and C. The developer team next floor is rolling their own thing to do C and D. All while features A and C are incompatible so it's impossible to satisfy everyone. There is no solution to resolve internal conflicts (except maybe reducing a large company to 20% of its current workforce).
