However, many other extensions have been added to OpenGL that became obsolete pretty quickly. I hope this won't be the case with OpenGL 3.0 too quickly. Even if the API might be future-proof, this counts for nothing, if vendors impatiently add their features. I have nothing against experimental extensions, that are clearly not for use in commercial apps and thus can be removed later. I simply don't like to have an extension, that is for a few months the de facto standard and then is hard to get rid off, since people already use it frequently.
