Yes, my message was incomplete. There is double tap on Sailfish X too, but it is disabled by default because it causes somme probable issues with sleep and therefore battery life (if I recall correctly). I'm actually fine with pressing/touching the same key without moving my finger to wake/unlock. The double tap to unlock was a nice feature that I miss sometimes, but in fact I liked it more when I didn't use a lock code, or when I forced myself into using one but had not tried the fingerprint scanner yet.
