Well, during my 727 training (which also carries a limit of 20,000' for
flap extension), we were taught that the limit exists because, during
Boeing's flight testing, the test pilots never extended the flaps while
above 20,000'. Since extending them above that altitude would be
venturing into uncharted waters, the limitation was imposed.

Just my $0.02.
