I don't think that's the case: v5.9.1 has been cut from the V5-9-patches upstream branch [1], which doesn't include the commit you identified as implementing support for ECC certificates.
I agree with Sergio in that we shouldn't backport this to Ubuntu, at least not during this development cycle. The feature hasn't even been released in any upstream release after all.
