On your home page (README.md), you have the following quote:
ECDSA support is nonexistent on OS X hosts unless your users build openssh from scratch (or homebrew). This is considered painful. This may not be a problem on more modern versions of OS X (i.e. high sierra) but I haven't tried it.
I can confirm that macOS Mojave comes with OpenSSH_7.9p1, LibreSSL 2.7.3, which supports all four key types (RSA, DSA, ECDSA, and Ed25519). You may want to update your documentation.
