That's a great way to get something going quickly.  Unfortunately, if
you don't understand the why's, you often end up making subtle errors.
These errors may cause bugs that you recognize and fix, or they may
cause vulnerabilities that you're not aware of.  It's not uncommon when
adopting a new viewpoint.  

I know it happened to us with Client Utility (e-speak Beta) when we
introduced "split capabilities".  Originally, we kept the parts
together, but later that got "optimized", and we ended up subject to a
kind of confused deputy.  If we'd understood capabilities better, we
never would have made that particular error.
