Then this is my first answer, the developer guidelines state exactly
what the performance string should looks like, and the label is usually
self-descriptive.

This string is meant to be machine-parsable and all the information you
need relative to a check should be in the check output itself. The
documentation is properly located considering that only people that
develop applications using this information need to know about the
details. There's no need for the users to know them beyond that it's
made for being processed by other applications.

If you believe that some checks are missing information then v3 output
and the new plugin thresholds should be the solution for it.
