I don't like the idea personally, but honestly the only advantage that i see with single Peter is he being able to be shipped with other women, althougth romance shoudln't be the main focus, just a way to keep the possibilites open.
For another side, Peter is always my main concern when it comes to the franchise, i haven't enjoyed Slott's run because isn't married, but because his voice for the characther really anoys me more often than anything else (hell his Doc Ock annoys me too and unlike many posters here i don't really care much for his RYV mini), i still don't know what to think about Spencer and Zdarsky is something that haven't checked out yet, if i have my way i would like him to be written in a similar way to what Millar, JMS, PAD or even Sacassa wrotte him back in the day, not necesarely with the same setting (married, school teacher, etc) but something resembling to that and better plotting, but i don't trust most modern writters this days so who knows what is going to come in the future
