This is google in a nutshell.

I lived near google for many years and knew many employees and this drives them crazy. In order to have innovation and support for a particular product, google allows engineers to do what they want until nobody wants to touch the bloated pos and everyone walks away.

Gmail has thousands of hidden functions. To get gmail built they allowed each engineer to add what they wanted...and most of it was for them personally. Remember the gmail2 thteat from a number of years ago? They couldn't figure out how to force every user into a new platform.
