It's... not obvious to me that that's a good thing? The ratio of configuration code to code in the things being configured being that close makes me think that BCL is something that's ill-suited to what it's now being asked to do but there's too much of it to realistically replace.
Maybe it's amazing and the problem it's solving is so complicated that even a language designed very well for solving that problem leaves you needing a lot of it, but I don't really consider "a staggeringly large amount of code has been written in this language" to necessarily be an endorsement of that language's quality. Citing Google's 300M lines of Java would also be a silly reason to pick Java in a project where you'll never interact with the Google ecosystem.
