This framework needs to convert > object demand (kmalloc() bytes, kmem_cache_alloc() objects) to pages. And hence the big idea that all reserve accounting can be done in units of pages, allowing the use of a single global reserve that already exists. The other big idea here is that reserve accounting can be independent of the actual resource allocations. This is a powerful idea which we may not have explained clearly yet.
