Hidden Kojima tribute in Metal Gear Survive?

Konami has finally released it first non-Kojima Metal Gear game Metal Gear Survive, and it appears that Twitter user @NourishedPsyche may have found a hidden tribute to Hideo Kojima within the game.
As reported by Gamegrin:

For those that have been living under a rock, Hideo Kojima was apparently sacked from Konami before the release of Metal Gear Solid V. What really happened is open for debate, but many within the gaming community have pointed fingers solely at Konami, especially after a highly anticipated new Silent Hills sequel was cancelled. It must have been a pretty big rock if you weren’t privy to any of this drama. Not even one with dial-up Internet.
The message uncovered in Survive was found by Twitter user @NourishedPsyche, in which there appears to be an anagram that spells “KJP FOREVER” 

IGN have also Added:

Underneath that, two of the names with particularly negative connotations -“Bastard Yota” and “Cunning Yuji”- share the same first names as Survive’s director Yota Tsutsumizaki and producer Yuji Korekado. Both are listed as “AWOL.”
Ouch.
Going a little deeper, if you take the first letters of the last names of ‘Iron Marlin’ and ‘Dire Gibbon’, you get ‘MG’ – or ‘Metal Gear’. Both soldiers are, tragically, listed as ‘KIA’.



KJP is widely considered – although not confirmed – to be the internal abbreviation for Kojima Productions. Could it be some old Kojima Productions developers paying tribute to days gone by?
