I was told that sshfs *does* handle .ssh/config.  Turns out that sshfs
spawns "ssh -s sftp" to get a SFTP subsystem channel.  Then it
directly implements the SFTP application protocol.

This way they don't need to link against libssh2.  They spawn ssh with
a socketpair on stdin/stdout.  They send/receive SFTP messages
directly.

The benefit is that everything works (options, host key handling, and
configuration files) like you'd expect from ssh/sftp/scp.

You may be tired of trying different alternatives, but perhaps
switching to this model is worth it.  It would solve these
integration/user friendliness issues that a libssh2 implementation
has.
