Delete unused shim config in RequireJS?

Question

OK, so my problem is that I'd like to be able to automatically delete parts of the shim config I've set up for RequireJS; rather than loading the entire minified Bootstrap file I split it up into the different plugins, so that I get the benefit of less filesize when my application uses less of the Bootstrap components. E.g:

require.config({
    paths : {
        jquery     : 'vendor/jquery/jquery.min',
        bootstrap  : 'vendor/bootstrap-sass/js'
    },
    shim : {
        'bootstrap/affix': { deps: ['jquery'], exports: '$.fn.affix' },
        'bootstrap/alert': { deps: ['jquery'], exports: '$.fn.alert' },
        'bootstrap/button': { deps: ['jquery'], exports: '$.fn.button' },
        'bootstrap/carousel': { deps: ['jquery'], exports: '$.fn.carousel' },
        'bootstrap/collapse': { deps: ['jquery'], exports: '$.fn.collapse' },
        'bootstrap/dropdown': { deps: ['jquery'], exports: '$.fn.dropdown' },
        'bootstrap/modal': { deps: ['jquery'], exports: '$.fn.modal' },
        'bootstrap/popover': { deps: ['jquery'], exports: '$.fn.popover' },
        'bootstrap/scrollspy': { deps: ['jquery'], exports: '$.fn.scrollspy'        },
        'bootstrap/tab': { deps: ['jquery'], exports: '$.fn.tab' },
        'bootstrap/tooltip': { deps: ['jquery'], exports: '$.fn.tooltip' },
        'bootstrap/transition': { deps: ['jquery'], exports: '$.support.transition' },
    }
});

Whilst the r.js optimizer correctly identifies that I'm only using bootstrap/dropdown, it still includes the shim config for files that don't end up in the production code. So my question is can I get rid of the unused shim files automatically? I'm using grunt-contrib-requirejs for the actual optimization and have had no problems with that. A Grunt based solution would be preferable but I'm open to anything else. Thanks.

To summarize the great points made above, and hopefully close the question

• Unused shim configs are not removed by r.js since it can't know if you need them at run-time
• ~175 bytes (gzipped) are not worth manually optimizing, especially as part of a payload 200 times that big, and won't cause noticeable improvement
• AMDClean could be an automated way to de-AMDify your scripts completely and thus meet your size-saving desires
