There are a few workarounds that don't involve undocumented APIs for this, as someone else in this thread mentioned.

Facebook's Groups app uses (disclaimer: as far as I can tell) an interesting technique involving saving data URIs to the home screen and then deep linking them.

This wouldn't be the first time they have been played given whom they've interviewed: a dishonored Nixon, a cadre of tobacco executives, and a bunch of confabulators from the US customs who claimed no drug trafficking between US and Mexico.
