Regarding which hybrid option should be marked by IANA as Recommended - I did some checking.
Using a browser that prefers X25519MLKEM768 I actively probed some of the most popular services (admittedly from a single location). The following currently accept an X25519MLKEM768 offer : * Google, Gmail, Youtube, gmaps * Facebook, Instagram, Whatsapp * Reddit * X (Twitter) * LinkedIn * Amazon, AWS * Yahoo * DuckDuckGo * Fortnite * Cloudflare hosted services * Akamai * Fastly * Temu * ChatGPT * Anthropic while the following do NOT (yet?) accept it : * Microsoft, Bin, Azure, MSN * Wikipedia, Wikimedia * Apple, iTunes, app-store * Tiktok * Netflix * Roblox * AliExpress * eBay * Pinterest * Yandex, vk, ok, rbc and many other Russian sites So, we have very widespread acceptance even without a Y in the R column.
