The problem with these sorts of legislature as I've experienced is that while the theory seems quite appealing it never really works as you would expect.
Canada did a similar thing a couple years ago. The CRTC imposed a law where an individual could only incur a maximum of $50 in data overage charges locally, and $100 when roaming.
I was ecstatic when this was announced. And then one month I went over on data by $50. And then my data was cut off until I bought a "pack".
So yes, your phone bill will be unsurprising at the end of the month, but now your carrier will expect you to purchase a bucket of "roaming data" in the form of an add-on or package to your regular phone plan so that you can post your selfies with the Eiffel Tower in real time.
That's still better than the horror stories you hear about people who went abroad with a torrent client running in the background of their tablet and rack up thousands in charges.
I would say that cutting of the data would be "expected behavior" as far as I am concerned.
