That’s three examples of software that are way more complex than they should have been for the general use cases.

Yes, a lot of software do continuous development, but in a more stable manner, where they introduce some features, takes time to iron bugs out, and then release a new version. Meanwhile, the users only have to care about some small security fixes every now and then. When there’s no new features (especially when you’re not creating a kitchen sink), things can be calm for months and years.

Personally - I think most software is way more complex than it should be.

Depends what you're working on, but from what I have seen software always gravitates towards "unmaintainable mess of complexity" - and our job is to steer the system AWAY from that mess
