Honestly, the biggest problem I have with the naming is that "Albus Severus Potter" is just an ugly, ugly name. Like, they could have given the kid something he can work with. Give him a decent first name and then saddle him with two middle names, or make his middle name Albeverus or something. Combined with the fact that post-war wizarding Britain probably saw an upsurge in kids named Albus to the point where it's overly common, and this poor kid is going to end up going through life as Skip or Boomer or whatever the wizard equivalent is.
