They weren't created to be solo events. So there is nothing job-restrictive about it. Entering solo is a courtesy and so was the creation of these fights for easier unlocking.

Players unable to properly plan for how to encounter these old bosses will need to figure out how they are going so wrong and/or team up. These fights are considerably easier than when they were released over seven years ago. Body and legs unlock specifically have mechanics which will punish players who choose to ignore them or fail to mitigate them.
