People don't just use this for "debugging sessions." They use it in production, and I already gave you one reason why you might not want to do this with netconsole (udp is unreliable, and I've definitely seem cases where netconsole suffered due to dropped packets; this won't make that better, especially when you multiply the extra bytes times the number of servers on the subnet).
