Self: 'static causes GAT outlives lint to needlessly fire

[BoxyUwU]

The following code (playground):

#![feature(generic_associated_types)]

trait Trait: 'static {
    type Assoc<'a>;
    fn make_assoc(_: &u32) -> Self::Assoc<'_>;
}

Gives an error:

error: Missing required bounds on Assoc
 --> src/lib.rs:4:5
  |
4 |     type Assoc<'a>;
  |     ^^^^^^^^^^^^^^-
  |                   |
  |                   help: add the required where clauses: `where Self: 'a`

I would have expected the where Self: 'a not to be required as we already know that Self outlives 'a as it outlives 'static
