I don't understand the argument against having to revisit the site and fix it in the future. Web design takes place from the standpoint of what is possible to accomplish with the most-supported features. From that starting point, vendor prefixes only allow developers to improve their product for users of more modern browsers, and in doing so, place a vote of support for the rapid completion of the prefixed feature. If you decline to use "-webkit-", you put your website at a disadvantage compared to others that do use the prefix, and you still have to return to the site at some point in the future in order to implement the feature once it's widely supported. I suppose there's an argument to be made for saving a little bit of hassle in the present time, but that's highly situational and since CSS is so easy I don't think it holds muster.
