Well, sort of. It makes sense to bundle language and display features, such as date and temperature formats, into a single locale. That's what other Unixy operating systems do. However, a locale is a display formatting issue. If the entire system needs to be restarted after a locale change, that's a sign that display issues are too tightly coupled to stuff going on in non-display code, perhaps in kernel space, and that should not be the case.
