Research direction

The payload names no source files or tests. Start by searching the package source for the calls to emptymutable and copymutable, then read the two linked upstream Julia issues (JuliaLang/julia#34677 and #46230) to see what public replacement or status Base has reached. Done means those internals are no longer used, or each call sits behind a clear fallback, and the test suite still passes. Confirm the approach with the maintainers first, because the outcome depends on upstream Julia.
