I havent looked at it recently, but the code used to be awful, which is perhaps where the rewrite comes in. But giant PHP applications with even more features are not really the future, these things need to be built as sets of APIs and libraries that you can put together to add the features you want (which are complex).

It is indeed still awful. I know someone who works in Magento and they frequently come to me with genuine WTF bits of code. Added functionality would be a nightmare.

A rewrite is sorely needed, and will help developers who have to work with and on Magento to save their bosses time and money.
