I suspect this is done for many reasons including you do not want to
distract pilots when they are landing. Just another example of an all
round impressive system.

The aircraft on the ground actually do transmit a signal, but alarms
are being suppressed for landing gliders as it would distract the
pilot too much.

Under what "landing" conditions are alarms suppressed? I'd certinly
like to be alerted to an opposite base head on with another glider or
a tug.
