    And all that for what reason? Because some people don't read the doc? If there was a technical solution to stupidity, it would have been implemented a long time ago.

    I fully understand that you don't see the problem because the solution looks simple. However such a change will translate to thousands of tickets and bug reports because "compilation fails" or "my script does not work" or "my docker compose broke". If there was any gain at all, there's a discussion to be had; when it's for dubious reasons, it's just breaking things for pleasure.
