The issue describes well the missing feature. Solution is based on #43074 (comment) As mentioned in #43074 (comment) it can be solved with PHP attributes already. If this became obsolete, feel free to close it.

Hey!

I think @NicoHaase has recently worked with this code. Maybe they can help review this?

Cheers!

We can also use #[Autoconfigure(tags: [['security.voter' => ['priority' => 3000]]])] but what about adding a #[AsVoter(priority: 3000)] attribute to make it easier ?

I like this proposal about #[AsVoter] actually. Would you be up to give it a try?
I feel like we could even deprecate these static methods in favor of attributes now.

Oh, reading the source, I figured out we already have an attribute for that: #[AsTaggedItem(priority: 100)] would work equally well.
Can you update the PR and its test cases to use+mention this attribute instead of getDefaultPriority()? I'm going to suggest deprecating this method in a follow up PR.
