Same here. I'd made some nice (and quite simple) tooling to parse docstrings out of a Python project and turn them into Markdown that I could copy-and-paste into Confluence. It was so convenient to run something like "make documents" to basically compile the project's documentation from inspecting the project itself! But then Confluence broke their editor by making it WYSIWYG-only. And in response, I broke Confluence by convincing our CTO to ditch that now worthless documentation system for something else.
