I got the feeling this plugin was for people who need to— for whatever reason, be it work or otherwise— make a lot of Wordpress themes. In that regard, it's pretty neat. I wouldn't go so far as to learn HAML and how to use the RVM just to make a friend a blog theme, though.
Still, I dislike how the programming community jumps on someone for making something interesting— even if it's not immediately useful for everyone. I get the same feeling in reddit's /r/programming whenever a post pops up about someone using a "NoSQL" database. It seems the majority of comments tend to be people negatively criticizing the OP's choice instead of providing something constructive to the existing project.
