The objective of testing on older browsers is to break feature testing logic.
For example, Opera 6 has no DOM Core implementation. Ergo, I use it to test code that uses the DOM Core to observe graceful degradation. This enables the code to be "future-proof", or compatible with past, present and future browsers.
