It's funny isn't it. I guess I don't try hard enough to find productivity-enhancing Vim plugins. I've tried various "Vim enhancement suites" intended to bring a number of useful plugins and had some success, but since I can't rely on them on new servers I find myself more often than not just using plain Vim.
Some other commenters in the thread have raised the point that having more supported functionality out of the box is a good selling feature. To me it seems that having it built it can (possibly) benefit from a more intentional effort to make it cohesive, whereas with many disparate plugins you have to encourage, force, or otherwise guide developers to build something that fits and behaves with the rest of the platform.
You've touched on an important point: taking inspiration from workflows and incorporating them into the core editor itself.
For editing text, there's already a lot of flexibility in Amp's keymap system[0]. As users compose more sophisticated/useful macros, we can promote them to the default keymap, and if they're really useful, we can build them as discrete commands in Amp itself. That way, the core editor evolves to encourage a particular workflow. It's opinionated, and it may not appeal to everyone, but that's kind of the point.
