Hi Matt, I think you are making a good point here. I wanted to expand Roller's AtomPub API to make it easy for me to manage blog posts and templates, adding support for categories made sense because entries must have categories. I think you are right that comment management is different and more concerning, due to potential prompt injection vulnerabilities. Maybe I should rip out the AtomPub comment management stuff for Roller 7 while we consider this.
