Imagine you have a global Drupal site with several languages. One market wants to add custom functionality for just the English language. From a technical standpoint would it be better to develop the custom functionality with multilingual capabilities by default?
I understand this is a high-level question, but was wondering on the pros and cons. The custom functionality would fit well with other languages, so two specific questions are for instance:
- Is the consideration of multilingual often more expensive than developing the monolingual version?
- On the long-term is it better to have the multilingual version from the start instead of adding it in a later phase? (updating code after functionality was pushed live).
