Whether I decide to restart or not depends, I think. On my current file, I'm only mid-way through Summer Y1. Ever since the announcement that 1.5 was coming out soon dropped, I vowed to not get too much further in the file until it's released. If any new starting choices mostly amount to a new farm map and the like, I'll probably stick with my current file, since I really like the forest farm. However, for example, if there's an option for the Farmer's birthday that can only be selected on the character creation screen, then I'll probably have to start over. I don't know how likely that would be, though. If that were to be a thing, there'd probably have to be some way to set the Farmer's birthday aside from the character creation screen.
