from `man bash`:

       GNU  rm,  like every program that uses the getopt function
       to parse its arguments, lets you  use  the  --  option  to
       indicate that all following arguments are non-options.  To
       remove a file called `-f' in the  current  directory,  you
       could type either
              rm -- -f
       or
              rm ./-f
       The Unix rm program's use of a single `-' for this purpose
       predates the development of the getopt standard syntax.

no, it's not a bug. 

    rm -Y

is functionally equivalent to

    rm "-Y"

and to
    
    rm \-Y

because of the way the shell hands the arguments to rm.  rm then
treats them as normal arguments.  `rm ./-Y` is the easiest way, but
sometimes that won't work.
