[Rd] as.data.frame() methods for model objects

Hello all, Would there be any interest for adding as.data.frame() methods for model objects? Of course there is packages (e.g. broom), but I think providing methods would be more discoverable (and the patch would be small). It is really useful for exporting model results or for plotting. e.g.:
