Why empty named graphs make sense

1/ Scenario:

A site publishes a page, in RDFa, with triples in it.

The site replaces that page, with one saying, "changes in progress, 
please come back later" with no triples.

Recording this seems like a reason to have empty named graphs.

2/ The default graph can be empty.

3/ A point made has been that N-quads can't represent an empty named graph.

A syntax fix could be:

_ <http://space> .

or other style indicate a space name.

To my reading, the spaces document works if "quads" are removed, not 
that I'm suggesting that.

How about defining as a convenience of useful vocabulary rather than 
core definition?
