As a maintainer, I don’t want my project’s documentation to use exactly the same theme as someone else’s. The layout and conventions should be consistent with other projects in the same environment (in my case, other Python projects), but it should still be possible to glance at a page and know that you’re looking at Project X, rather than “a project styled using the default Sphinx template.

Об этом я уже писал, но цитатка слишком яркая.
