It does give extensive rationale: not only is it easy to configure (much easier than OpenVPN, let alone anything IPsec), the trusted codebase is tiny, and the cryptographic protocol is significantly more trustworthy. Respectfully: I suggest you check out the research and design that went into wireguard first, because he trustworthiness of the two protocols is not the same just because you’re unfamiliar with it.
