Parsers aren't particularly difficult to write, and even if a hand-coded parser might not be very efficient compared to a generated one, it's unlikely to be a significant factor in the overall performance of the application. Compared to the complexity overhead of adding another dependency, be it a library or an external parser generator, i feel it's a fair trade-off.
