I am not very familiar with Git community but I think including a new feature to use our existing library (who's functionality isn't required as for now) can trigger some creative thoughts in minds of other developers which will make them think "How could this be used?". This could lead to some exciting ideas on improving the UI of git. Having something actually in hand gives you a confidence, rather than knowing that you could grab it whenever it is needed. Also, when such an idea for new feature comes up, it is better to implement it because let's say some developer is stuck in future and this new feature could help him but he doesn't have a clue that such a discussion happened some time ago. Thus saving him time and further effort. Anyways, How is the convention in git for these type of futuristic ideas? -- To unsubscribe from this list: send the line "unsubscribe git" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
