Clearly they're in the business of something else because the product isn't very compelling when it comes to browsing and searching. You need to be able to build the code to even have a chance at that level of understanding of the source. And really you need to be able to build the code with a specialized toolchain. This is tractable with a huge investment if you get to choose or dictate your tools. If folks are bringing their own tools it is basically impossible. Pushing for standardization of fact output from toolchains could be a path to getting somewhere when you can't dictate toolchains. Or really just having some kind of fact output from default toolchains would get you a long way.
