It's also still being offered on the 777, as far as I know.  My
understanding was the part of United's reason for not ordering the
option was the weight penalty -- 3,900 lbs., or 2,000 for just the
hinges and stuff without the actuation mechanism, which allows easy
addition later on.  United preferred the weight savings and even at
that went with a higher MGTOW version in order to operate the 777
on Chicago to Hawaii routes, which are right at the range limits of
the A-market 777.
