You're right. It even has a small icon to show users to do that. Guess I was quick to judge.
What I never understood, and is a function that has carried over, is the 'Horse Search' function whereby you click on a horse that is racing and it takes you to the Horse Search page where you can see the horse's racing record, instead of the HRA Online page. This means if you want to check a horse's breeding from that page, it's an extra click or two to get to HRA to see progeny.
