This is much broader.  For example, I cannot write a derivative called
"Brian's Xdebug" or "Xdebug manual" or even "A third-party manual for
Xdebug".

Excluding a singleton name is fine.  I'd even go so far as to say any
excluding any countable set is fine.  Excluding an uncountable class of
names is not.
