Which is fine if you don't want deniability, and probably desirable for legal signatures. But that doesn't make it something with no value. Parent poster was claiming it made no sense to want authenticity and then publish the keys. I'm just pointing out that there is a desirable property which uses that approach. And HSMs can be (and commonly are) configured to store keys which can leave the device, though setting a specific time lock is not something I think many support.
