I think it is useful to have specific tags about job titles that
do have a specific meaning in parts of the world that use that title.
lecturer is not ambiguous to people in systems where that's a job title, just as
assistant-professor is not ambiguous to people in the US. On the other hand,
junior-faculty is not a clearly defined job title and
is ambiguous (look at the current state of
early-career to see what I mean by this...) —
