Yes of course, but dmidecode and the current DMI layer implements
both anyways, don't they? (ok if you don't count the dynamic interfaces)
The tables are very similar, there are just more entries in SMBIOS.

That's two fields out of hundreds. Does that need a common layer?
Right now I still fail to see the point of all of this.
At some point I wanted a slightly more expansive sysfs interface for SMBIOS
to avoid having to start mcelog as root for reading /dev/mem, but I don't
think such a complicated approach is justified for that. What are
the other use cases?
