Well, Ben Pfaff has provided one example where parenthesizing a macro
definition interferes with it's intended usage. A parenthesized string
literal is not a string literal, and will therefore not be merged with
adjacent string literals. Many string literal macros are intended to be
used in the construction of larger string literals, so parenthesizing
them would interfere with that use case.
