For this reason, should we move to a "printer-firmware-update-col" (1setOf collection) and have each collection specify an ID as well as its own support URI, urgency, etc.?

Maybe? The current printer-firmware-xxx attributes are separate 1setOf attributes with the ith value stuff, and I was under the impression that the new printer-firmware-update-xxx attributes were extending those to report when a new version of a firmware component was available...

Using a collection is cleaner but might be overkill if we decide that reporting a single set of values for whatever updates are available makes more sense.  At least one of the vendors I work with does monolithic firmware updates of multiple components because of how the firmware images are managed (whole read-only system images with A/B partitions), so if I added support for the new attributes to that product it will always show "no updates" or "N updates" (and nothing in between).
