(Biased: I help work on lcl.host) It's very very very nice to have real TLS from the start to the end of a project. Doing actual HTTP/3(QUIC) with real TLS and catching CORS issues on my box without any complicated tooling/setup is pretty dope. I'm doing some Go-based MTLS right now and it's been a breeze getting all the cert bits wired up. Kudos.
