Deprecate <svelte:self>?

[brunnerh]

Describe the problem

<svelte:self> has typing issues and should not strictly be necessary since components can import themselves.

This being the case I would suggest removing it in the future unless there is a good reason not to (e.g. not all common build tools being able to handle such imports).

Describe the proposed solution

Deprecate <svelte:self> for 5.0, remove later.

Importance

nice to have

I remember trying something similar and failing for some reason. Otherwise very in favor of deprecating

I've reached for svelte:self maybe a total of 3 times ever, so I like deprecating it in favor of self-referential imports.
