It seems a bit awkward to have to use a property group itself as
though it were a boolean property, rather than having an actual
property.

Since SCF doesn't admit the possibility of temporary properties, and
since having the system clear out a persistent property would probably
be too hackish, did you consider creating a "config_ovr" temporary
group with the new flag as "config_ovr/fastreboot_default"?  The
design for the "general" property group seems to use this scheme:
temporary settings go in "general_ovr" (a non-persistent property
group) and permanent ones in "general."  Things that have to deal with
those "general" properties look in both places.

One other very tiny nit: "_np" as a suffix has historically meant
"non-POSIX."  Are we sure we want it to mean "non-persistent" as well?
