an excellent suggestion, also possibly a bidding process... but I'm sure none of the US tech companies will champion this option because there is already room to do this unofficially within the current program... 50,000+ yearly visas gives a lot of overhead above just seeking "truly exceptional" talent.
Big tech companies can play the lottery, smaller ones can't.
And I don't see any need for a bidding process, which implies a fixed quota, a fixed closing date for the bidding, and a lot of uncertainty.
Just require the salary to be high enough to show you really need the skill, not to cut costs, and have a process with a guaranteed timing and outcome.
