Rewriting stuff from scratch is seldom the answer indeed... Which makes it worse if it looks like the current platform these great apps are written on depend on the work of one, increasingly frustrated person. I know that, for instance, the gimp people are working on GTK3 support, but they also have to contend with really bad bugs and lack of support for Windows and OSX. I don't like that situation one bit. Porting gimp to Qt was a demonstrated possibility way back in the closing decade of the last century, I doubt the feasibility of that at the moment.
