Speaking as an operator: it does. Adding freeform text to NOTIFICATION messages with code "Cease" with subcode "Administrative Shutdown" would be very useful to tell the operator on the other end of the connection what is going on. Trying to define all the possible values would be impossible because of the huge variety of ways operators work together, and limiting the possible values would limit the usefulness. Freeform text is therefore appropriate at this time, and UTF-8 encoding will allow us to write messages in a language appropriate to the situation.

Cheers,
Sander
