I recommend reading the wiki and judging for yourself.
When I contributed a binary QR code decoding feature to zbar and the new version landed in the arch repositories, the first thing I did was edit the arch wiki with usage information.
I also documented a process for encoding and decoding PGP keys to and from QR codes using that feature by editing the paperkey article on the arch wiki.
When I installed arch on my laptop, I wasn't able to configure my screen's brightness. Searching the arch wiki revealed that by default the kernel's Intel iGPU drivers would set brightness by PWMing the screen which doesn't work over eDP connections which is what my laptop used, and also documented the exact kernel command line option I needed to make it work.
