Never really understood using a template language when PHP is first and foremost its own template language. I also don’t understand developers making decisions now about things that might one day have to be replaced. It’s like building a bridge, but letting the plan to maybe have to tear down the bridge 50 years later dictate all the design decisions.

The fact this happens to lead to more organized and testable code masks the wastefulness in the original goal of such an effort. It simply trades back-side efforts that may or may not ever be required for additional front-side effort with the result of making things easier later if it happens to be needed. I’m not saying it is completely a bad thing, more that it isn’t de-facto a good thing either.

I guess, like with all things, the important part is finding the right balance for the situation.
