Verification done on jammy-proposed.

1) a system/hardware vendor tested and confirmed that:
   - systems with SMBIOS 3.5 report the new fields as expected;
   - systems with SMBIOS < 3.4 keep the old fields as expected.

2) I tested on several physical and virtual machines, and:
   - systems with SMBIOS < 3.4 keep the old fields as expected.
     (see details below and in next comment.)

Physical machines:
- Supermicro AS -2024US-TRT
- Dell PowerEdge R730xd
- HP ProLiant SL390s G7
- HP ProLiant DL360e Gen8
- HP ProLiant DL360 Gen9

Virtual machines:
- Multipass VM
- LXD VM
- OpenStack VM

cheers,
