I was missing that option as well, not only using obj.library but after ctrl+shift pasting solids on surfaces. Scaling around bounding box center would mess up the surface alignment.
The ability to scale the object without losing surface alignment I'm missing the most in the whole MOI. I am a concept / industrial designer and MOI is seriously lacking in that. I cannot express how much time I am losing to readjust it and sometimes it is really hard if the surface has an odd angle. Michael, please help us out. It has been years. Thank you!
I asked for this some time ago and now it's a reality. Thanks so much, thanks so much Michael! It's not a typo that saves me so much time! Much appreciated!
