I wish you convinced me of that in the 1980's 
I blew my low back out big time doing heavy deads.
I can see some possible benefit in back thickness doing controlled form pulls from lower knee ht in a rack.
If you blew out your back that was your fault, there are only 3 reasons why you would get injured doing deadlifts, bad form, lifting a weight that you cant handle or trying for one more rep after your muscle is fatigued, if you avoid these 3 things you will never get injured doing deadlifts.
