The original 32 MB default size is just way too undersized and most homebrews, even basic ones, require to manually increase it making developing for Vita from newcomers just counter-intuitive.
128 MB is a best choice for a default value since applications very intensive with sceKernelAllocMemBlock can still lower it using _newlib_heap_size_user and at the same time it offers a good balance between dynamic memory available through newlib and memblocks.
