Get out! I have never heard that one before.
Hmm that would be really unlikely for performance reasons.. Though if they applied a combo of the grass code and the mushroom code, it'd work.
I've wondered about and tested more insane things.. I once tore down a dungeon and then rebuilt it exactly in a new spot (same z-level) to see if it would 'spawn' a new mob spawner. It didn't occur to me that if the old dungeon can't regrow a spawner then why would a rebuilt one?
Still I had friends that were 'terrified' of the rebuilt dungeon so close to town and insisted it be demolished. The same friends made me build a 'safe room' for the nether portal in case things started coming through it. ;p
