I'm one of those developers, and I think it makes sense to write documentation for Claude and I have no issues with that.

The point of self-documenting code isn't to get rid of the documentation. Instead, it's to integrate it into the code. This fixes the two biggest problems with documentation. First, that the code will often be updated and documentation left behind, making it useless. And second, that English and code are intertwined in the same document, making you constantly switch mental contexts of how you are reading. So no, I don't consider developers who write documentation to be inferior. If anything, I value documentation even more, and the purpose of self-documenting code is to make the documentation better, not get rid of it.

With Claude, the documentation you make for Claude is just fine as it doesn't run into any of the above two problems. The documentation isn't being left behind, because you add to it instead of the code. And it's not intertwined with code, because you are just writing English for Claude, you are not writing code in-between.
