It is a website. With forms. And logic to query a database. And do math.
Aggregators are capable of asking what city, date and time, how many bodies, which service class, which seat, etc. and returning your menu of options with prices based on those details.
Yet asking "how many bags" and multiplying that by the airline's rate is impossible?
Of course it requires changes. I suspect those happen now and then.
My point is that airlines would be able to find something else to withhold by default and charge for if you tried to mandate bag fees be displayed up front. A fee for being allowed to recline. A fee for getting to sit behind someone who isn't allowed to recline. The list goes on and on.
However, then you can't argue anymore that "the market" will handle it. Because even the theory behind that requires that market participants are informed - which they evidently aren't.
