I think there might be a misunderstanding about the scandinavian concept of microbevel. It is established after the grind has been sharpened. After the sharpening, it's a few very light passes on the stone on steeper angle, it's not a double bevel in the sense that you would only sharpen the bevel. I agree that it weakens the blade's performance on wood, but only slightly, unnoticeable to most, while giving strength for a hunter's blade to work meat, tendons and bones and the such. It will also make a scandi grind very much useable for edc.
As to sharpening a scandi grind, I have not come across any problems in sharpening it (in comparison with other grinds), haven't ever noticed it requiring more time or effort. The larger flat does help in keeping the angle correct and therefore keeping the blade's performance good for a long time. Most mistakes occur when wrong sharpening tools with very little knowledge of technique is used on these blades, but that goes for any grind. In my opinion biggest differences in sharpening come from the steel and it's heat treat. As with all blade edges, if you let it get real dull, it will require a lot of effort to get back to shaving sharp.
