The commonality is that there are various required or optional
fields to fill out.  I actually have a WIP series to make the tag_set
dynamically allocated and refcounted to fix some long standing life time
issues.  That creates a new alloc helper that will take a few mandatory
arguments and would heavily clash with this series.
