Optics are contextual to a certain extent, but my sense is a lot less than most assume. Again, the distinction between a routinely successful hunter and a backpacker with a rifle must be maintainted. For example:
A riflescope is never going to be good for anything (besides it's intended purpose) other than a quick look at an animal. The laws of optics simply do not permit a scope to have the eye relief required for use on a centerfire, a practically useful field of view, and anything approaching acceptable weight and size. Pick two of these, at best. The old timers who have tons of heads on the wall and use a scope as their only optic are not proof that this is the best system, just that skill and experience can be good substitutes for technology.
An adaptable tripod with a decent head and bino adaptor makes a massive difference. I really can't overstate this. I'm skeptical, to put it mildly, that any lesser system has enough weight savings to merit the associated increase in fiddling. The Summit SS I use works for standing and sitting on all sorts of uneven terrain, and sets up in a matter of seconds to a very comfortable position. This kind of rig encourages thorough glassing with good technique.
Spotting scopes are probably the most negotiable item here. I've left my behind deer hunting plenty. In many circumstances it is invaluable, and indeed the little Minox I've been using this year is in desperate need of replacement. Even in ideal conditions 30x magnification is nowhere near enough for alpine hunting when, as someone mentioned, evaluating legal horn size is all too often a big deal.
My stove number was indeed for a rig which could melt snow, and function in windy temps down to single digit F. On early season trips you can often manage just fine with an alcohol rig or similar. Insofar as later-season extended trips are the real proving grounds, I used that metric to guide my gear selections (esp layering).
