I don't use the link modal either, and really couldn't care less about the Title field being there or not. I only wrote the first version of the plugin as an exercise in how to modify some core javascript. I've learned quite a bit from doing so. Not a JS guru. :)

In any case, I support users having choices, and if somebody wants that field back, then by all means, a plugin to put it there and make it work simplest it is the right way to go. In the process, we discovered a few minor core issues making things like this somewhat difficult to do, and with any luck, we'll get those fixed for 4.3 as well. So, well worth the time spent on it, I think.
