I've been doing this since VM/SP3 (before there was a VMLINK EXEC).
Every software package and every release of that package has its
own mini-disk. If something is found buggy in the new release I
can quickly change the linking EXEC to link to the previous
release mini-disk.
It's also nice to be able to switch back and forth with the
releases to compare results.
And it makes it easy to install a new release of VM. None of my
EXECs are on what I consider to be IBM owned disks like the Y/S
disk.
