Sure but I mean it's centrally registered in the central WHOIS database. Of course the registrar has whatever data you put in their order form, that's obvious enough; what I mean is that they still forward your personal info to a central registry and the only thing GDPR changed about the WHOIS database is output filtering, or in SIDN's case not even that. I find it totally weird and invasive that this must be centrally registered in the first place (I grew up with my parents telling me not to use my real name anywhere online, let alone put it in a public database; maybe the problem is that I wanted a domain as a teenager and now it weirds me out?). Using privacy options means my paid-for domain is now not legally mine and I can't make use of any dispute procedure because the registry organisation has nothing in place for when my real name is not tracked in their database.
