There are certainly benefits for the company but between predominantly revenue-centric attitudes and a lot of poorly trained "senior" engineers I wouldn't trust the majority of companies (outside of Google, Apple, Netflix, and other great engineering orgs) to do it well. Independent schools dedicated to progressing the craft and tools would benefit more, I think.
