I am in the camp that HX did no less than it is required to because normally airlines' websites do not show transit visa requirements where more than one flight is involved. E.g. if I need to transit the US, CX, HX, BA, Expedia and so on will not remind US requires all transit passengers to have visas or ETSAs.
