Just recently back from a 4 day trip in snow covered alpine conditions using a wood burning stove as a primary cooking source, this worked out great.
As far as your concerns go :
A. Would adhere to any rule park/forest service would have in effect, these stoves are self contained but would choose cooking area carefully to be on the safe side.
B. Carried Tinder Quick firestarters and a few Esbit tabs in case of wet conditions, never used Esbit
Tinder Quick ignited small twigs just fine.
C. Carrying a small mug could be an issue for this type of set up, would have to modify a commercial model such as TriTi cone, possibly by building your own you can construct something to work with a small pot.
D. We were up 9,000-11,000’ and usually would start to gather wood as our group trekked toward the later part of the day if we were not sure of any source where we would be camping.
E. Experience was on a 4 day outing, initial response from the group was these stoves are fantastic, provided a great overall cooking experience, highly recommend.
