Lemmy has no data portability mechanism, does it?

In the stock Lemmy web client there is apparently no mechanism for users to fetch their history of posts. The settings page gives only a way to download settings. This contrasts with Mastodon where users can grab an archive of everything they have posted which is still stored on the server.

Or am I missing something?

IIUC, there is no GDPR issue here because no data is personal (because all Lemmy accounts are anonymous). But if a Lemmy server were to hypothetically require users to identify themselves with first+last name, then the admin would have a substantial manual burden to comply with GDPR Art.20 requests. Correct?
