You can have your Porch, and setbacks too …
Will be interesting to see how this plays out in practice.
The idea is that a house on a corner lot can’t easily have a wrap-around porch because of lot-size limitations, so now the encroachment into the front setback (an encroachment which everyone who’s ever enjoyed a conversation on a shady porch with a neighbor can probably support) can wrap around to the side setback as well, encouraging a more “connected” style of home much like the traditional homes of yore.
Overall this seems like a good thing. But “what defines a porch?” will likely become the question. What do you think?
