Tools like this to me reinforce the broken state of TLS in the modern OS stack. This looks great, but it's insane we need to do this: TLS really needs to be a kernel level, global feature. Take it out of the hands of applications, and let's add a pluggable system which extends the socket interface directly since that's theoretically what "transport layer security" is.
It's already hard enough to use web from Windows 2000 and other old operating systems. Making TLS kernel level feature will likely halt any TLS progress. Google is moving TCP to user level (QUIC) for a reason.
So we wind up in this space where a transport level protocol is for some reason being handled by the application stack, in a million different places and only somewhat common by convention (which we've gone and broken with containerizing userspace).
