Actually, I firmly believe that this applies to big apps as well. From my experience, if there is an app a user needs and it requires the user to upgrade their browser? They will upgrade their browser. Most don't upgrade because nobody asks them to. If a need arises in a corp environment to use an app with the simple requirement of a modern browser - they will upgrade it. If the apps always "allow" sub par browser support and bend over backwards for it - there will never be a reason for people to upgrade.
