The more I look at ContentHandler, the more it seems like a major new feature for MW.
Are there any examples of this in use on Labs?
Is there more information on how to use and extend it for things like WorkingWiki?
There is some talk of how the Gadgets extension may be changed by the use of ContentHandler. Has any work been done on that yet? Do gadget authors on-wiki need to know about these changes?
I like what I'm seeing in ContentHandler, but I'm a little afraid that this will be like the introduction of ResourceLoader -- there is a lot of promise here and new capability, but it sounds very disruptive to current Gadget users (to give one example).
How can we begin to prepare third party users of MW for these changes now?
