Enterprise software tends to have lots of features that the majority of folks will never encounter in their career. The enterprise market space is composed of around a thousand potential customers world wide, all of whom are large enough to have sophisticated and complex internal computing environments. They have varying norms, requirements, workloads, regulatory environments, industry standards and so on and so forth.

Each has a lot of money and rejecting the requirements of one company often means you are effectively rejecting several, or perhaps even an entire sector. So you add something to cover them and before long, your software has the union set of features required solely by enormous companies.

From a non-enterprise view a particular feature may seem like absurd overkill. But someone, somewhere, needs it and there is a long and often impressive story of how it was achieved.
