I really like bitwarden, but I do wish their internal API was more clear/open so 3rd party clients were easier to write. There have been a few times where I've been on an obscure OS on a device too slow to run a modern web browser, but wanted to use Bitwarden.
As another perspective, by documenting that API, they're promising to retain backward compat and the documentation burden that comes with it. As long as it remains an internal API, they can fiddle with it as fast as they can get their old codebase off of it
Since their codebase is in the open, and there's already at least one other Open Source implementation, that's likely about as "clear/open" as its going to get unless this newfound $100M spawns an API team or something
