Have you called around for such a service? You may have to pay through the nose but it could be out there.
It's like washing a car with 500ml bottles of Evian. It works but it's not what it's meant for.
I rarely tether. So what does this mean regarding unlimited data (non tethering)?
Two floors.
A) No celluar tablet
B) no unlimited mifi/data only sims
Agreed. Using tether for anymore than 10GB/m mean you should have a dedicated service IMO.

They'd need their own infrastructure...
Why do you believe they'd "need their own infrastructure"?
Network congestion may have played a part but it's more than likely that the ditch of 'unlimited' tethering has occurred over costs, ie - cost of bandwidth outweighing money coming in from customers.

So the problem 3 have found is that some people do just use too much data and a significant chunk of this is via tethering. So they have to do something about this as it is an unexpected cost, which is their right as a company (obviously special circumstances are needed for people mid-contract)
The simple thing would be to restrict the amount that could be tethered, rather than to cancel/put a charge on tethering.
So leave it as an unlimited data contract, but only 2GB of that per month can be via tethering.
The 99% of people who don't use more than that via tethering have the convenience of tethering but at very minimal extra cost to the company.
