Based on list seems builtin functionality is what is used to work with processes (nohup, kill, etc), environment (where, which, etc), and for shell as programming language ([, while, etc).
Yes. As an example, the source builtin would not be possible to implement as a command as a child process can't change its parent's environment. So those types of concerns play in I think.
