Some system admins prefer to have everything on dmesg, as they can enable a serial console, and catch the logs remotely, even when the machine crashes for example due to a hardware failure.
So, IMHO, one feature that the perf event needs is the capability to report errors via a serial console also, or a mechanism where some events are sent via dmesg.
