This is incorrect.
I'm coding a Lemmy clone right now and have been testing this functionality out extensively. Deletes of posts and comments certainly federate.
I haven't tested what happens when the 'delete account' button is clicked... Mastodon solves this by sending a 'delete this user' Activity to every fediverse instance so it's doable.

Deletion of entities is optional in ActivityPub. That, by definition, makes known-removal of an account and all its posts in one go impossible, because a server can just ignore the deletion activity.

Yes, although the server will not ignore the deletion activity if that server is running Lemmy. We're talking about Lemmy here, not the fediverse as a whole. OP singled out Lemmy in the post title and said "lemmy devs are not concerned with..."
I'm sure there is more to be done in this area. It'd be great to know for sure which software treats deletion activities properly (I'm really unsure about Kbin, I think it does not) and which does not so instance admins can make informed decisions about who they federate with. Perhaps this information could be made available right within the UI that Lemmy admins use to control their instance, rather than an obscure documentation page somewhere...

How would you even know if deletes federate?
Tell me: how much closer are you to knowing if the server is caching or not?

As long as a deleted post is no longer visible in the publicly-accessible parts of the site, that would be enough verification for me.
I don't know how the GDPR authorities verify compliance with mainstream proprietary closed source apps, do you?
