In terms of cutting performance, angle makes a larger difference, but the range of sharpening angles used is fairly narrow, whereas I have seen edge thickness more than a factor of a hundred, so yes, it makes a lot of sense to take a look at the edge thickness. Alvin Johnson was the first person I saw discuss this on the internet, back on rec.knives years ago. It also make a *massive* difference in how quickly the edge sharpens.
Yes, the Mel Sorg knife I have with a full convex grind, 3/32" stock, is limited to soft materials. It has a lot more narrow a scope of work than the NIB design with the secondary edge bevel. Better steels allow you to work in a wider range, but geometry can still limit usage in extremes. Reasons to carry more than one knife.
