The "G" in GTK+ stands for "Gimp". If Gimp is using GTK+ ver 2 who are we to say different? Perhaps ver 2 is the version and the rest are just pointless forks..

This is a serious question in general. There will always be s steady stream of significant upgrades/changes of any popular open source project as later developers add in things they consider important. At some point the decision has to be made to stop following those changes. This decision is usually made by default when it turns out that no one can be bothered to follow the changes of a project from another project.
