I don't know if Kelley would agree with my characterization, but I don't see comptime as metaprogramming. Instead it opens the very interesting possibility of having types as values, as long as those values are resolvable at compile time. This lets you do things that feel like metaprogramming (e.g. making a generic container structure) but it seems a better conceptual fit to me that you're programming with types as values rather than generating code from a template or macro.
