Refinements have a very significant performance overhead. The simple fact of refining a method, even if the refinement is never used will make calls to that method 40% slower. On rarely called methods in doesn't matter that much, but I18n refine some popular Active Support methods, so any project including the I18n gem suffer from a significant performance penalty. See this benchmark for more details: https://gist.github.com/casperisfine/1c46f05cccfa945cd156f445f0d3d6fa In the end these refinements are easily replace by simple module functions taking one extra argument.
