[Rd] Should dots be used in generic functions?

When writing generic functions, should "..." arguments be routinely

The Writing R Extensions manual says that if it is used, all
descendant methods must use it too.  In most cases in the R library
source, the generic has the dots, often documented as parameters for
the descendants (e.g. profile does this).  In the case of profile, the
descendants declare the dots, but don't make use of them.
