The only reason to use (10)GE for transmission in WAN is the completely
baroque price difference in interface pricing. With todays line rates,
the components and complexity of a line card are pretty much equal
between SDH and GE. There is no reason to overcharge for the better
interface except because they (all vendors do this) can.

We've just ordered a new WAN to be built, and we're going with GE over
(mostly) WDM because the interface prices are like six times higher per
megabit for SDH. (which would have cost roughly equally per line given
that it is quite OK to run SDH without the SDH equipment, just using
WDM)

Oh, s/SDH/SONET/ on above, but I'm in Europe, so..
