Firsts, minification feature is already implemented in TYPO3 4.2. Secondly, there is an extension that can minify/combine JS and CSS files together.

The drawback of such things is that they happen at runtime, thus making the performance of the server worse. Minification of the JavaScript using PHP is extremely inefficient. When possible it should be done separately before deploying the site.
