I appreciate your level response. You're correct that these features are not absolutely, always necessary for success. I would caution that even with a an incredibly compelling core feature set, you still have to negotiate yourself out of not providing these features. Even when you win you might be creating a maintenance nightmare for someone down the totem pole within your customer's org. Part of what we're trying to do with EnterpriseReady is show that many of the non-core (yet common among many enterprise customers) features 1) aren't that hard to understand 2) can be built really well in a way that will delight your users.

* As the OP, when you say: "some are just something someone added to a list because they thought it sounded like a good idea" - I genuinely hope that I did not do that.

100% - Always be thinking about security.
