I have several of those projects. I avoid dependencies as much as possible, striving to only use things which I know ship with my target OS. I code for a level of correctness and longevity. That benefits everyone, including myself.

A QR (or barcode) library is exactly the type of thing I’d assume would still work fine, since there’s nothing new to do, the parsing rules don’t change, it’s a static, known, solved problem.

I agree with you - and yet the barcode library I used recently for a variable-data-printing project was last updated 13 hours ago, despite having been around since 2008!
