I like scandi grind a lot, in fact it is my favourite, at least for "bushcraft" tasks, always in 1/8 inch though! Sharpening a scandi will result in a slight convex bevel, whether this is contributing to a stronger edge, I doubt! However, it makes most tasks a bit easier or convenient, particularly shavings etc. I try to avoid a microbevel since it defeats the purpose of a scandi. I try to maintain my scandi edge with a thin leather strop and compound, or more recently with HeavyHanded's washboard. When I need to resharpen it, I use a Norton Crystolon or JWS. I baton all the time with my scandi without any adverse effects - but, I do it very reasonable, more specifically no knots, thin enough diameter (about an inch) etc. Never had a problem. A scandi with a 12.5 dps bevel is not a block smasher, nor a can opener, nail cutter or screwdriver. It is a cutting tool.
As stated above, the actual apex only initiates the cut, right after the shoulder/flat part takes over pushing the wood apart, no more contact for the edge unless knots, twisting etc. That's why one can use a fine scandi grind at all for this.
