Since WHEN have appliance manufacturers dictated FIXED WIRING STANDARDS?
If they said 1.0mm rubber and lead cable, and a 5A rewireable fuse would you hack out the wall, run a new cable and rip out a brand new
17th edition consumer unit so you could fit a 1950's wooden one bought from the antiques section on Ebay?If not then why would you change the correctly designed electrical protection of a perfectly serviceable 6mm cable on the whim of an appliance manufacturer? By some of the ridiculous responses in here I suspect a few would!
