Since the information was committed knowingly and willingly to the public domain, though I do not know much about it to begin with, I don't see how GDPR applies at all.

You could IMO also make an argument that the collection and scraping of WHOIS data without consent was unlawful processing as a whole, as the data was not provided to the domain NIC with explicit consent for third-parties to collect and save them forever, which would even make any overriding legitimate grounds for processing moot.
17a may also apply: The reason for WHOIS is to find out who owns a domain now, right? There is no version history. Historical WHOIS data does not serve this purpose anymore.
It's quite the can of worms.
