There's an old proverb that the best time to add i18n support is today. It takes a bit of extra effort to build new stuff with it in mind, but that little bit of extra effort today goes a long way (and builds good habits) versus the large projects to add it tomorrow when it becomes tech debt and needs a full audit of every possible way a string might be formed for display to a user, because you just got a client/customer who needs it tomorrow.
