I seem to see a general consensus that some effects generated during recovery don't resolve until the draw step?

i.e. "Gone but not forgotten"

Why is this.

No one has priority during the wrap up, so the soonest that any powers or modifiers can trigger would be at the start of the next draw phase.

Effects generated after the start of the recovery phase cannot resolve untill all players pass without taking an action.

The only time players can pass is when they have priority, which they do not until the start of the draw step.
