GTIA trigger 4 input disconnected on 2 controller 5200. Important?

[the Goat]

I just installed the Sophia RGB mod in my 5200.  When I opened the 5200 I saw that all the main DIPs on the motherboard were already socketed.  And one of the pins on the GTIA was bent up so that it was not inserted into the socket.

 

I checked out the GTIA pinout and saw that the bent pin is the trigger 4 input.  My 5200 is a two controller variant.  So I guess the GTIA trigger 3 and trigger 4 pins are unused?  What do people make of the bent trigger 4 pin?

Got no clue why any pin would be bent up but both my 5200’s are 4-port models. 
 

All 5200’s should be fully socketed, just like nearly all Atari, Inc. computers and consoles (some Vader 2600’s are soldered rather than socketed). It was only after Jack took over that sockets started generally disappearing from Atari Corp. products - a sad carryover from his ruthless cost cutting days at Commodore.
