I disagree. Here is the information tracked by Heroes Profile when it comes to damage taken. The specific information is from a SL match I played over the weekend as Johanna.

For the red team, they had only one front line hero, and their back line was taking almost as much damage as their tank. The blue team had a tank/bruiser setup, and you can see that our back line were pretty much allowed to do whatever they wanted without worrying about their health bars.
As a tank main, I find this sort of information useful as it can tell me how well our comp worked, and if I am doing my job directing as much damage as possible to me. If I am the one taking all of the punishment, something which my hero is designed to handle, my healer can focus on healing and weaving in damage, rather than frantically performing triage, and my DPS aren’t spending the entire team fight running for their lives, but bringing on the pain.
Of course, the usefulness of data is fairly subjective, but to call it strictly personal is a bit misleading.
Edit: This kind of breakdown can also point out positioning errors. If a ranged assassin is taking a lot of damage, they may be constantly putting themselves in bad places.
