I can't imagine that. Think of embedded applications. When you only have 2MB of flash and a couple of megabytes of RAM, you really start to care about the few kilobytes such a feature costs of both memory footprints.

RAM and flash ships get larger and larger all the time. For smaller design companies it may already be cheaper to get 4mb than 2mb flash chip.

But of course the code size matters. Smaller code implies better cache usage.
