This was already explained during the 2.x development process. In the
new multiprocess architecture, the DOM tree lives in the WebProcess
while your application is the UIProcess. Synchronous communication
between both (as DOM bindings will require) is not (generally) allowed
between these two processes because they must not block. Apple for
example decided to reimplement for Safari all the use cases where they
used their DOM bindings.

Said that, it's still possible to access the DOM :-). The solution is
the new WebExtensions API developed for 2.x series. You'd basically have
to define a extension (kind of a plugin) that will be loaded by the
WebProcess (so it can directly access the DOM) and that could talk back
to your application using D-Bus or whatever method you like. Check for
example ephy-web-extension.c [1] in the epiphany source code which
implements the "save passwords from form" feature among others.
