Most other compiled languages do dead code elimination, which sounds similar but is a little different. Think of dead code elimination as removing code that doesn't change the output, while tree shaking instead includes code that could run.
To apply this to python is interesting - if you were creating a packaged version, I could see "compiling" the code to a separate package with only the required imports.
