Some of us are attracted to new technologies, and appreciate learning the lessons of what advantages or disadvantages come from building the same type of site or app with a different framework or technology stack. Especially those of us who aren't yet mature enough to write our own apps without the guidance of frameworks, and have not had a chance to work with all of the different possible approaches.
I think a healthy balance can be struck between the type of stability gained from the 'boring' approach, and the types of gains that can be realized from newer 'non-boring' technologies. Sometimes supporting IE6 is not a concern at all, and learning new language features from ES6 is an attractive proposition.
If doing front-end development were boring, I don't think I'd be as interested in doing it.
