It's not so simple. There are multiple scenarios. The author might go on a hiatus and the translator catches up. Is that a completed status or what?
The translator is fast and the author is slow but still consistent. Do we automatically set to Completed when the translator catches up to the "last" chapter available?
There is actually an automatic mechanism that IF no new chapter is released for 30 days, Privilege chapters will be released on a daily basis, but most people don't even wait 30 days before they complain, and I bring it up to Webnovel that this book is completed.
To know whether something is completed, it needs a manual check, and with hundreds of translated works out there, it will be a waste of manpower to check everything manually. Don't forget, you will need to compare with the raws to see if it's on hiatus, really completed or what. It's on the translator to inform Webnovel that the book is completed and some groups just forget the book once they finish translating it (perhaps months before the final chapter is released for the masses).
