Not an economist, but that does not sound bad in general. Best case you have several companies that: (a) have the knowledge to make sensible rulings and (b) have an interest that non of their direct competitors gain any unfair advantages.
The problem case is when the companies all have a backroom meeting and go "Hey, lets ask for regulation X that hurts us some... but hurts everyone else way more"
Economists actually shouldn't even be included in regulatory considerations in my opinion. If they are then regulators must be balancing the regulation that on its own seems necessary with the economic impact of proper regulation.
It hasn't worked for the airline industry, pharmaceutical companies, banks, or big tech to name a few. I don't think its wise for us to keep trying the same strategy.
