Yeah, for most recent ethernet devices it's
more-or-less mandatory.  If you look in 'net/eth.c'
you'll see that many of the newer drivers only have
their code within the confines of #ifdef
CONFIG_NET_MULTI.  This code needs an overhaul, and
for other reasons too, but as with much of U-boot it
has to be done very carefully to ensure
backwards-compatibility.
