There was a problem hiding this comment.
I think the new wording makes more sense, as the current one is very confusing.
I was having a quick look to see why this error message appears, and it's due to the fact that the +/* ZPP specifiers (and the fast ZPP Z_PARAM_VARIADIC equivalent) don't support the named parameters. And it doesn't seem like it's very easy or even sensible to migrate to the Z_PARAM_VARIADIC_WITH_NAMED fast ZPP specifier that does support the named args.

I was a bit confused when I encountered the error
does not accept unknown named parameters.The issue was that I passed an associative array to a variadic parameter, which made the message misleading.
Because of that, I felt a clearer error message would be more appropriate in this case.
I changed the error message from
<function> does not accept unknown named parametersto<function> does not accept named arguments for variadic parameters.The discussion about this problem was touched in #11026
