If Thomas has enough time to finish it (bearing in mind the hundreds of hours it will take to bring it to production quality) - and if he has time to maintain it over the years - and if he is able to commit to years' worth of future maintenance - then this could become a very nice and usable implementation.

I think it's great when people write something for the love of it.

For a high quality TLS implementation that is production-ready, and has had extensive third-party verification and certification, I'd recommend mbedTLS from ARM.
