I decided to go ahead and switch to the Dojo Toolkit. It provides almost everything I need and the next release looks very promising. It took me about a day to do the switch, but now I'm happy it's done. I had a chance to go over the code (as I was converting) and improve it.
This means I'm not going to improve JSForms further. I'm going to take svn down, but I'll keep the wiki and the website for some time. However, there will be no further updates.
I'm not going to stop writing JavaScript and I do want to contribute to the Dojo what I can. I also think I'll continue to write about it in the future.
