Honestly I do not see any significant difference both in the
level of verbosity for the annotations and in the quality  of the help
message provided in the absence of annotations. Originally plac too
was able to recognize flags automatically by looking at the default
value (if the default value is a boolean then the option is a flag);
however I removed that functionality because I wanted to be able to
differentiate between flag and (smart) options (see
http://micheles.googlecode.com/hg/plac/doc/plac.html#scripts-with-options-and-smart-options).
