I'm asking you what do you think about it, not what the devs think about it. Let me phrase it differently, there are a total of 16 languages and 276969 lines of code in the repo for a "soldering iron firmware"
As far as LOC goes, I know well enough that it's a meaningless statistic that has very little practical use. I've written 34 lines of JavaScript that were as meaningful as 25k lines of C, but those lines of JS were obviously interpreted on an engine that's millions of LOC.
