It also proves that such solution external to the language is possible. That
weakens the case for a language feature

That is always the reason, but every feature must be implemented tested,
supported, and may clash with future extensions.

"it wouldn't hurt", and a bit of typing, and some fairly theoretic case
about readability are IMHO quite weak arguments.
