Amateur ARQ modes are 'session' oriented. That means one and only one connection at a time can be made between stations. Each station checking in would have to 'make' a connection with the net control station and then send callsign, etc. A 'disconnect' would then have to be done to allow the next station to log in.
With ARQ there is no way to either send information to a station or to respond without making an actual connection. In order for the net control to dispatch stations off frequency to handle traffic, he/she would have to 'connect/disconnect' with each station to send them this information and to get a positive response that the dispatch was received. All the 'connect/disconnect' messaging really slows down net operation. As far as I know, none of the FEC modes require the 'connect/disconnect' operations to send and receive information which makes it much quicker and easier to control net operations.
