OP here. Seems like they're setting up fixed loot tables for specific mobs. (certain mods will drop from specific enemies). This new system will be a great improvement once they implement it right. Right now though, the drops are still pretty wonky and I'm sure isn't working as intented. They're working on it though. Here's a post by DE_Steve regarding the matter:

"Warframe friends-

The crusty Titans of the old RNG have been defeated by new RNG Gods. Update 9.5 (with subsequent adjustments coming in the next hot-fix) features a completely new loot table implementation.

OLD: Per-faction massive table with hundreds of entries of varying rarities.

NEW: Per-enemy table with half a dozen entries of varying rarities.

Yes, rare Mods are still rare. Yes, we still are tuning values (it's raining Chassis blueprints)! No, farming Xini will not yield every Mod in the game anymore... you gotta mix it up.

Thanks for your patience as we tune the new system!

ISSUES WE ARE WORKING ON: -Blueprint and Resource drops from bosses is out of wack. -Some UI to learn this stuff. -Fusion Cores rarity. -Proper attenuation for harder enemies dropping rarer stuff."
