I would appreciate that feature, too!
In Virtual Box, you can set scaling to 150%, and that will be fixed. Now you can still resize the window, the resolution of the virtual machine will also be changed.
If you set stretch mode, you will alwas get a blurry picture.
I am using many linux guests and always have problem with their scaling, so I wish to scale within vmware workstion.
mksft did you find a solution?
