I ran into the same issue but worked around it slightly differently: have my code use RDAP, and then have an RDAP->WHOIS proxy [1]. There are usually rate-limits on WHOIS, so public instances won't survive long, but it works for me and you can run locally. I also hunted (s/whois/rdap/g) around for undocumented RDAP servers and found a few. There are still a lot of TLDs without RDAP though [2].
