RIP exploration.
1. No. Rip going off without planning properly for exploration, and packing some AFMs.
2. The original vision for exploration was that it was meant to be challenging (hyperspace routes requiring discovery and plotting, temporary bases being set up for repair and resupply etc.). I think it disappointed a few people (self included) that Sag A was reached so easily, without requiring any form of planning logistical support. Jumping around like a frog on cocaine without actually looking at what's out there too much doesn't strike me as exploration.
3. Exploration was still undertaken in Frontier/FFE with wear-and-tear/failures implemented and no financial incentive to do it in game - humans are weird that way.

Having said all that I've said in this thread, I can see wear and tear not being implemented simply because, like module price degradation on resale, people have gotten too used to it not being there, and would play heck on these forums if it was changed (though I'm pleasantly surprised Frontier got away without reverting the shield cell changes so far
