You assume wrong, however, TSLRCM did edit the loot scripts so perhaps the "new" implants you are referring to are already existing implants made droppable. In the normal game level, 1 implants CON are 12, level 2 implants are 14 and 16 and level 3 implants are 18 I believe.
Bit of self-advertising but you may want to try my Implant Feat Restoration mod- http://deadlystream.com/forum/files/file/1047-implant-feat-restoration/ it removes the CON system and replaces it with the K1 style 3 feat system. It "may" have small bugs here and there but it works. This isn't part of TSLRCM because Obsidian intended to cut this content and TSLRCM wants to make the game how Obsidian intended so this will remain a separate mod.
