The other difference is the use of the faster adler32 checksum in deflate instead of crc32 in gzip, so *if* we want to mandate something, deflate is cheaper for both ends. That said, I'm still very concerned that we want to mandate such antique bit-oriented algorithms which are extremely slow and memory invasive while we have many much better ones such as snappy, lz4, quicklz and I-don't-know-what which are much more friendly for both ends and better suited for the 21th century's machines and networks.
