I'm wondering why get_free_pages allocates contiguous pages for non-DMA transfers and why the kernel identity (ish) maps the whole (up to 1GB) of physical memory to its address space...

I can't answer the question as to why, although I suspect because it's a lot
easier,

I can say, however, that if gfp were to not return contiguous pages, it would
break my driver.
