That's still an open question. Language shifts like this take time to stick. But .si itself isn't new or temporary; it's been a real, established domain since 1992. Even if the term doesn't catch on everywhere, you still own a short, clean two-letter domain.
Registration is open to anyone, anywhere, with no local presence requirement.
