Yes, it would be. Just an idea: we may get a lot of mileage out of a
generic method for adding or augmenting, and removing kernel property
lists from a kernel, either at run- or compile-time.
Consider that much of the VERBOSE info is in tabular form, thus
expressible by property list. So are PCI/USB/... vendor/product tables
that we use to match drivers with devices---I wish we could change
those tables without recompiling. I anticipate using property lists
to express device locators. So it seems to me that "linking" property
lists into the kernel could be very useful.
