@pwuille I spoke to @hashbreaker and @hyperelliptic and the said we can do HD Keys with 25519—just multiply result by subgroup (i.e 8).

Fri Jan 08 06:29:39 +0000 2016

There were many compromises necessary to make TLS a standard—none of us back then thought it would take 17 years to deprecate SSL 3.0 usage.
