The B727 has a similar restriction. I was told that the restriction exists
simply because, during certification testing, the test crews never extended
the flaps above FL200. Therefore, to prevent your everyday airline pilot from
venturing into the unknown and becoming a test pilot, the restriction was
placed in the AFM.

Hope this helps.
