This is not part of the upcoming release.
Hiding is nicer than adding not-ready disclaimers throughout, especially
since this information is very easy to access via our beta channel.
The doc/api is a legacy name, which is confusing in the current use, since all build targets are now APIs.
Today we have:
doc/common: Common configuration and settings between all targets.
doc/main: Main Pybricks documentation at docs.pybricks.com.
doc/ide: Documentation shipped with the Pybricks Code IDE.
