The issue with just position="attributes" and redefining the context, is that again, if two independent modules do it, they are incompatible unless a third module accounts for both of them.
But with this module, an extension point can now use position="attributes" and instead of redefining the "context" attribute, you will now just define a new "context_foo" attribute. This module modifies the web client in such a way that before sending the Ajax on_change event request to the server, all the node attributes starting with "context" are merged into a single context dictionnary, keeping the keys and values from all extensions. In the rare case a module really wants to override the value in context, then it needs to still override the original context attribute (or the other original attribute).
