We added explicit public API to the robot.api package in RF 7.2 (#5245) using redundant import aliases like from robot.parsing import get_tokens as get_tokens. That has worked well and we should now do the same with the robot root package and all sub packages. Most important reasons are:

• It is in general a good idea to specify public API. Not all sub packages are part of the actual public API, but even internally explicit APIs are good.
• Linters complain about normal imports that aren't used. Using redundant import aliases or __all__ avoids that, and we decided to go with the former approach earlier. We want to do linting as part of code formatting (see Automatic code formatting #5387).
• Explicit package APIs ought to help with IDEs when they add automatic imports.
