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?

I think in terms of gdpr, if you notify a site that is providing service (allows users to register from I guess) to EU countries you want something deleted, they need to comply.
But I think in terms of federated content, you cannot be expected to do more than send information about the deletion out. If other instances don't respect it, it's not the originating instance's job to police it.
Now the user could go to these other instances and chase it up. But I wonder if a third party instance doesn't allow users from EU countries, if they'd be required to comply? Federated content opens up a an interesting set of scenarios that will surely test privacy laws.
I also wonder what the EU powers are to sites in non EU countries that allow EU users but don't respect GDPR. what can they even do? Companies like twitter, Facebook, reddit etc have presences in EU countries that can be pursued, but John Smith running a lemmy instance on a $5 vps might be out of reach.

Short of having someone inspect the databases, they can’t. The GDPR is a threat, basically, that says “if (or, rather, when) the truth outs, we can nail you later”. Which is why it’s really only effective on big players anyway.
