Looks like IANA tries to fill up all the blanks with markers of "unassigned".

Is that harmful?

Minimally, it's redundant. Also, it only makes sense on certain types of registries.

I just checked the XML version of the first registry, and, indeed, it contains entries for unassigned values. /me shakes head in disbelief.

What *should* be done is computing the unassigned ranges for *presentation*; that is, they should not be part of the actual registry. The way it's done currently defeats one of the reasons of having a machine-readable registry (consumers will have to hard-wire knowledge of the specific "unassigned" entry to make sense of the registry).
