This is usually EMs in my experience.

At my last job, I remember reading a codebase that was recently written by another developer to implement something in another project, and found a thread safety issue. When I brought this up and how we’ll push this fix as part of the next release, he went on a little tirade about how proper processes weren’t being followed, etc. although it was a mistake anyone could have made.
