Only if a node contains information it carries information.
An empty node is as usefull like 42.
OSM is a community-project, so it means no one should insert
information that can not be used by others.
If s.b. searches for missing streets in the region how should one
search for hints by other mappers? Search for all empty nodes?
May be others use 4 empty nodes for a building and 5 for an missing
area and then there are trillions of empty nodes from broken software.
Many applications make usefull things with fixme-nodes
* there are markers on gps-devices
* websites highlighting fixme
* josm is shipped with some extra support for fixme-nodes
* and lots of more
Another well-established way is to use openstreetbugs:
Everyone can write here "street contiues 2km to west"
