The focus of IPP Privacy Attributes v1.0 is definitely on Job and Document attributes since those are supplied by the Client on behalf of the End User, and are processed by the Printer. From a protocol and processing standpoint, Printer data isn't considered PII because the service is configured to be available on the network, and things like Get-Printer-Attributes are available to anyone that can reach the Printer.
From a Client print spooler perspective, however, Printer information can be PII and in my former life as an Apple engineer I did a lot to limit the amount of information that got logged or stored by default by both cupsd on macOS and printd on iOS.
Saying anything about Client "processing" of Printer data would certainly be new ground for IPP...

I don't have any objections to deprecating it, but I am aware of some driver systems that are using IPP as a replacement for SNMP, but they still depend on 1284 Device ID for driver matching, and taking this away from them would cause them to look elsewhere. Then again, we are deprecating, not obsoleting, so it is still "around".
We dropped printer-device-id from IPP Everywhere. Whether we deprecate the attribute is something we can talk about, but as you say there *is* a purpose for legacy printers/printer drivers.
