As I said in #26486 (comment) and people wonder in https://symfony.com/blog/new-in-symfony-4-2-acceptable-request-formats#comment-22747, I don't think this method clear and generic enough to be added to the core.
I can't see where I would possibly use this method. What would be useful is a similar method that accepts formats as argument and would return the ones that are acceptable according to the accept header. This would then allow to make use of `*/*` and this is what people usually need in REST APIs etc.
But for now, we should revert it before it gets released like this.
