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.
