I could be wrong, but IIRC there is a limit on how much power can be delivered over USB-C that is arguably easy to hit for powerful laptops. Perhaps that's one reason among others. --- Edit: Could the downvoter explain the downvote please? Edit2: Quick googling tells me USB Type C supports upto 100W power delivery [1], while an example laptop, such as X1 Extreme Gen 2 can go up to 129W of power draw under load [2].
