Could this be a useful option- if you have selected a slightly small
field for an out-landing (ie- leave the u/c up?)
Another scenario, perhaps if you find the glider rolling along at high
speed towards an obstacle, then retract the u/c! Expensive, but maybe less
painful?

The landing gear is there to protect you. Use it for that purpose.
Gliders with decent brakes commonly stop faster on the gear than off the gear.
