If memory serves I've removed the Pkg.info file from standalones and 
they continue to be see by the Finder as bundles.

This ADC page describes the ways bundles are identified:

--------------------------------------------------------------

How the System Identifies Bundles and Packages

The Finder considers a directory to be a package if any of the following 
conditions are true:

     * The directory has a known filename extension: .app,
       .bundle, .framework, .plugin, .kext, and so on.

     * The directory has an extension that some other application
       claims represents a package type; see “Document Packages.”

     * The directory has its package bit set.
