To that end, I've been reading random websites with information about Elder Scrolls lore. I discovered this today:
The Green Pact has also heavily impacted Bosmeri cuisine, combat, and weaponry. They have developed methods of fermenting meat and milk to develop powerful alcoholic beverages and weapons such as bows are often made of treated and shaped bones. Most notable about Bosmeri combat is their stipulation that a combatant must consume an enemy's corpse within a short time after killing them. This has led to changes in approaches to combat, such as fasting and planning family feasts following a battle.

Now maybe I missed something in my old journeys, but in no Elder Scrolls game I'm aware of are Bosmer characters prohibited from practicing Alchemy, from dabbling in wortcraft, or from eating vegetarian meals, for that matter.
And as for consuming the corpses of fallen enemies, that would actually be easy to implement. There's a "dispose of corpse" function in Morrowind already, eh-heh....
Is the lore I quoted inaccurate, outdated (i.e., from an earlier Era), or is the Green Pact simply ignored? Is it perhaps not enforced outside of Valenwood?
More to the point, why would Bethesda pen such a restrictive belief system for one of the premiere races in its cRPG series? (This lore would be fine in a pen-and-paper game, but not an electronic one wherein it's difficult or impossible to simulate the restrictions and still allow players to progress through the game normally.)
