In my opinion, it is HTTP and WS LB rather than Application LB as it supports just two protocols. In contrast, if you look at F5 load balancer, it can look at LDAP packets or Diameter packets and do a L7 load bakancing. So ALB seems misleading terminology to me as HTTP and WS != All L7 applications
Judging by how Amazon has handled other things, I wouldn't stick too hard to that conclusion. They tend to focus first on something generally useful and easy then come back to fill in more difficult/less popular options over time.
