Then there was the chromium random DNS query string usage, which I first spoke about at DNS-OARC in 2019 [2] and VeriSign later wrote about in 2020 [3]. My guess is that queries for .alt would be less than the chromium "feature", since negative answers for .alt would be cached by resolvers at least unlike the random unique strings from Chromium.
