I think we have different meaning of plenty.
Commercial entities doesn't really map to one person. I thought WHOIS would have to be amended to be compatible with GDPR anyway.
I mean, you could create a website dedicated to mapping your current IP to yourself if you really wanted to, but that is hardly relevant.
I'm not sure about the other RIRs but ARIN, at least, has (had?) a requirement that any assignment of a /29 or larger must be reported (see "SWIP" [0]).
In other cases, a PTR RR for a single IP address could be enough to personally identify an individual.
