If you want the reliability you open yourself to the eventuality that you might have to put in some of the work to achieve it. Things like SPI, I2C and GPIO can be expected to work with Nerves + Elixir Circuits. But some hobby hardware is definitely not straight forward since they tend to have libraries only in Python. I've ported one such myself (Inky eInk display) and many others have contributed similarly. Nerves is good for hobbyists that want a better workflow and more serious and reliable setup. But it focuses on solving for production devices of you compare it to Raspbian.
