I was also told that the reason why these dialogs are modal is to stop 
users from editing the document while an extension is running, but not 
sure of the implications if the document is editing while the code is 
running...

The changes made will get overridden. The Extention takes a copy of the document, transforms it, and then replaces the document with the new document.

In settings there is a "Dialogs on Top" setting under "Windows" for how aggressive Inkscape is at pushing them to the top. Adjusting that may make it better (or worse). Perhaps GNOME needs a different default setting. Also, this is a lot of custom X code, so it'll need to die when using the Mir or Wayland backends anyway. They shouldn't have as much trouble enforcing modality as there is on X. At some point we'll need to decide when X11 isn't an important target.
