[texhax] \protect in LaTeX2e

In section 2.6 of Kopka & Daly's book, they state that "The issue of 
fragile commands ... with LaTeX2e has become of academic interest: all 
commands that are likely to be used in moving arguments are now robust." I 
recently discovered that this isn't true: \nolinebreak is not robust and

\caption{Blah blah ... blah\nolinebreak\ blah blah blah}

fails rather dismally. This can of course be avoided with \protect, but 
should \nolinebreak be instead made robust?
