The Mastodon API document is not intended to create compatible APIs. It is intended to create an application using Mastodon's API.
After seeing your(s) point of view, I felt "part of the information necessary for creating the application is undocumented", so I provided a short 1-line PR.
I just revealed the undocumented part, so I think that there are no Mastodon applications whose implementation will be changed by this PR.
