No, I’m imagining cross-language usage. Someone not using Go isn’t going to use the crypto/tls package from the Go std lib regardless of its quality. The overhead and difficulty of calling into Go make this infeasible.
To include a library written in another language as a shared lib, it needs to be C, C++ or Rust.
Golang users would?
That aside excellent points about rust tls, and libssl legacy cruft.
