Respec Feature?

Do you guys think Fallout 4 devs should add a feature that lets you respec your perk choices if you want to? I'm sure there's probably a mod out there that lets you (or if not there will be), but I still think it would be neat if Bethesda made it an official feature. Like something the doctor lets you do, or maybe a feature in the Memory Den, I dunno. It would just be nice to get to try out different playstyles once you're already higher level and have a good stash of weapons and armor instead of having to restart an entire playthrough whenever you decide you want to try out a different playstyle.
