I wouldn't be bothered about it either if the language, like Java, targeted more the development of long-running services rather than interactive applications (with some exceptions like mobile). But as far as I can see it is advertised for use in interactive applications, possibly as a Python alternative, where responsiveness is important.
I haven't got the same perception - I think it's aimed at things like simulator and solvers. Those things tend to have front ends (that is true) but not front ends that support 100's of users.
