Exactly.  The fact that some users have more bandwidth means exactly what?  Most people also have faster processors and disks now.  It is more efficient from a networking perspective to minimize unnecessary traffic and use local processing.  That was behind the rationale when delta was introduced and made the default.  It was valid then, and it is valid now.  You don't change the default without following the proper process.
