I'd like to know what use this suggestion would be if it was implemented. At best it would produce data which could be altered in an instant and be out of date very quickly. Additionally, there is no chance of this data being used as basis for a bet, either back or lay.
The increased use of spoofing, manipulation of markets by bets placed without them ever being matched, would seem to make the suggestion worthless.
What am I failing to see, please ?
Anyway, if it is implemented, it will not affect me unless I actually use it, I suppose.
