They have been doing for years.
The last time I was up front in an Airline Cockpit as a guest (before
9/11) during a none stop flight from Duesseldorf to Toronto, a
decision by the crew was made regarding a precautionary fuel stop.
Even though the flight could have gone the distance with ease, there
would not have been the legal amount of reserve fuel on board at
arrival in Toronto. Everybody was ticked off. But the winds were much
higher then forecast even though a different altitude was requested to
mitigate
some of the effect.

appears the airlines are using minimum fuel as much as possible to
reduce fuel burns and costs. Seems to me that some good glider
experience could become a hiring requirement at the majors if they
keep this up.
