sure, slewing is a possibility, but the launch by tug or winch is part of the fun and is essential for the immersion…
Furthermore I do not agree that the flight model of gliders is pretty good, it is far too sensitive and the planes seem to have the weight of feather 
I started my pilot career many moons back in 1972 with a glider licence and if I want to “fly” a glider nowadays I use the excellent Condor simulation program, now in version 3 already.
For viewing the undoubtedly nice scenery in the MSFS (both versions) I would prefer to fly the drone camera, haha
