I tried to add TLS support to libtirpc, but I think it's simply not
possible. The APIs are just not compatible.
Ganesha folks also tried the same, and failed - their ntirpc would
require a major redesign to support TLS.

So, why do the NFS folks even bother with NFS over TLS, if it is this
kind of mismatch?
