Well, not quite useless:  consider the possibility of a customized CD
with install script that can be run on a number of platforms.  As the
installer runs it notes the presence of /dev/mpt0 and then uses "mptutil
show adapter" and  other commands to determine type of controller, state
of volumes (if appropriate), etc.

A perfectly reasonable use-case, in my opinion.  But, in general, VMware
is an important enough platform that I suggest that mptutil should made
to play nice.
