yes, avoiding runtime costs is the real problem.

docstrings are mostly oneliners (at least in elisp)

Other applications are methodbrowsers/tabexpansions showing additional infos.

Or tooltips in IDEs when hovering the mouse over a method call.

PODs are not DRY, the subname must be repeated, docstrings are automatically at the right place.

    It shouldn't be.

    Avoiding imposing penalties on 99% of people's code that have no use for such esoteric facilities, to satisfy the 1% that thinks it might be a good idea, should be simple.
