I think your approach is the easier and more sensible one. I've had tons of issues with various caching plugins causing trouble. I also think a responsible Wordpress developer should not add any plugins without careful consideration, as each of them could be a security problem. (personally I generally stick to Advanced Custom Fields and at most a handful of other plugins. In many cases the former + manually adding a library and a bit of code to a theme is sufficient)
