It's quite likely that wrappers will need to allocate memory to marshal data back and forth between C and Elisp. If I wanted to build a module to use GMP, for example, I'd want to use GMP's low-level primitives that don't do memory management, and have the wrapper manage memory itself.

I suppose some wrappers won't need to manage memory at all, but I'd say most libraries need memory, and the overall system will benefit from having a single memory manager rather than having each library manage its own memory independently.

Have you used the Emacs memory profiler?
