Prop 224 encrypted public key
In prop 224 the "HS-DESC-FIRST-LAYER" is is encrypted to prevent a attacker from discovering the onion address of the hidden service, but even though it is encrypted it may still be possible to log the ciphertext of the "HS-DESC-FIRST-LAYER" every single time someone visits The hidden service. Through that they can determine how many people are visiting the hidden service, using that information on how many people are visiting the service, a attacker may be able to determine what type of site it is or use there nodes "researchers have set up nodes to capture the .onion addresses of hidden services" that they own to block traffic to any of those hidden services. The HS-DESC-FIRST-LAYER " Ciphertext" needs to be padded/obfuscated so it is different every single time a new user tries to decrypt it.
