Yeah, I thought they already had this. For a while it was sort of half branded under Picasa and half under G+/Photos but I set it up last winter for my girlfriend's mom. She has a load of scanned photos and digital camera photos on her laptop but no backup plan. Since she didn't want to buy a NAS or subscribe to online backup, I set it up so imported photos were backed up to Google+/Photos. Same stipulations: resized (but still decent) photos wouldn't count toward any limit but original resolution would require her to pay for Google storage. She agreed that the free storage of resized images was a decent compromise. Chances are she won't need the backups but if her laptop's hard drive dies then at least she will have decent copies of all of her photos. For a free solution it wasn't a terrible deal. She's not a photographer or anything so the smaller (but again, still decent) images would suffice for the cost.
