Except, the second example doesn't work with Augury as it is written. You need to take the queried course of action within 30 minutes. And I'm not sure if the results also need to happen in 30 minutes (which would invalidate the first example as well), but in either case, asking about a decision you'll take within a week is a no-go.. . . because it's been an horrific adventuring day, all the high spell slots are used up, there's a balrog out there - somewhere - looking for you, and you'd really like to take a long rest? "Should we camp in this seemingly safe dwarf-crypt?"
The DM knows where all the traps are, all the wandering monsters, knows all the NPC motivations, and how the forces of nature will strike. "Can I conscript my farmers one week later to give them time to finish harvest (or do they need the training right now)?"
That's the thing. If this was a less limited "Let's read the bones and see if this is a good idea" spell that can be applied for a far longer stretch of time, I think it could work. But the 30 minute time frame, as well as there being only four options (one of which, weal and woe, seems 90% more likely than the others), render the spell useless in my eyes.
