This is so weird to see. Just this morning I was checking thru my public authoritative NS query logs, and noticed the random capitalization. I had also noticed this in a similar work environment roughly end of 2023, but attributed it to people just doing DNS wordlist bruteforcing to find stuff (couldn't explain the case, but figured it was some evasion). Today I let my curiosity dive deeper and quickly found the ietf publication on 0x20 encoding and this article. Just odd to see others post it to hn on the same day.. coincidences are weird.
