Not so easy.  Would require to put the way openssl is integrated upside
down.  Today openssl is configured and the results (header files etc)
are committed to the repo, so the openssl config is the same for
everybody.

Also I expect there is no way around ecc long-term.  WPA3 was mentioned
elsewhere in the thread.  For TLS it will most likely be a requirement
too at some point in the future.  With TLS 1.2 it is possible to choose
ciphers not requiring ECC, for TLS 1.3 ECC is mandatory though.

So I doubt making ECC optional is worth the trouble.

take care,
  Gerd
