Anything else that is useful to know when adding (such as optional features the library may have that should be included)

AFAIK this one of the few actively-developed C++ libraries that I'm aware of which implement and provide examples for developing applications that take advantage of the QUIC and, more importantly, QUIC-based protocols such as WebTransport.
It depends on BoringSSL, Abseil and potentially other libraries.
