You think you'd be doing someone a favor by enabling them to carry on for a little longer without learning to communicate in English, but in reality, all you'd achieve is closing many many doors that otherwise might be open for them in the future. Not just things like good jobs and scholarships (which itself should be reason enough for any young dev not speaking English yet to drop everything else they have planned and focus on learning it). Not knowing English will make it much harder, if possible at all, to learn and become really good in what they're doing. If you saw a developer who had to stop drinking whisky each morning because their hands were shaking so badly they had trouble hitting the right key, and you decided to help them by creating a special keyboard, easier to operate with shaking hands, that would be a similar kind of charity to your "inclusiveness".
