I think the challenges with mushrooms as "whole foods" are similar to that of greens (also "good source of protein").
Challenge one: you need a truly huge volume of the uncooked stuff to get a meaningful amount of protein out. Lentils are way more compact.
Challenge two: when one cooks greens or shrooms, they tend to add a lot of oils and other stuff that destroys that ratio.
The proposal on offer here solves this for shrooms by preparing a packaged patty based on them (like today's extant Quorn product). This is cool and I'd love to see it, but it's not like they're trying to replace soy/lentils (which certainly have "good enough" protein content) as agricultural staples that you can harvest and eat with minimal preparation.
