Because it makes them feel in "control"...

Flying 2KA (Duo Discus with Lynn Alley) out of Salt Lake a week ago in the
wave we were squawking 1202. When we got to an area of high jet traffic we
called to SLC approach and let them know we were there. Even though we were
the only glider with a transponder flying in the area that day they still
moved us over to another code to keep track of us. Interesting.

Actually, I suspect it is to allow them to tie the glider ident to the
target in the data block shown on the display. Then they know that you are
two kilo alpha instead of just that glider with the anonymous transponder
code.

It is also that much better in case another glider comes along in the area.
