I can't see them being anything but proud of that legacy! In fairness they tried with IA-64, but the world didn't want it. And perhaps both HP & Intel were half hearted about it.
IA-64 was a terrible fit for anything other than carefully targeted code for very specific algorithms. Anything data-dependent ended up with poor code density. It was left to AMD to deliver the 64-bit instruction set that people actually wanted.
IA-64 was not a clean break; it was an enormous bet on compilers getting sufficiently smart by the time the cheap gets out. They didn't. In fact, today's compilers are still not smart enough to make the IA-64 a reasonable architecture.
