Wild Fauna breeding questions

So, I know that in the Guidebook Wild Fauna are treated similarly to Lone Wolves. To breed they need to meet MERs and get approval, all that jazz. This makes sense from a "we don't want parents to run off and leave baby players alone" perspective.

1. What was the discussion behind this for animals that are raised solely by the mother? If the father is a moot point, why bother with MERs? Maybe this hasn't been discussed yet?

2. How does the approval process work if the young are meant to be NPCs, then placed as adoptables when they reach maturity? What if the cubs simply die before reaching maturity, is approval still needed?

I ask these questions because for many Wild Fauna characters (including Umi here), yearly or bi-yearly breeding would be normal and expected/realistic for the species, especially since many NPC wild fauna exist in game.
