Great ! You've cracked it and I've learnt that blue messages are info and not warnings.
I checked the EpubCheck.json file in my Linux box and you're right - "usage":true
I then went to my W10 box and found "usage": false. I set it to true and voila!, W10 also announces that epub:type value "backlink" is unrecognised.
Curiously, I have no recollection of ever having edited the EpubCheck.json file in any of my machines. But now I have, I've set "usage": false on all boxes.
