Part of the problem here is that people incorrectly say (and this includes some BA staff) that the WT+ seats are the old Business Class seats and people then assume that they are the same as the Old Club Cradle Seats.
They aren't obviously and were specifically designed by Recaro for the WT+ cabin. Whilst there are similarities with the old Cradle seat - they are much smaller.
Unfortunately this myth has been perpetuated on many other travel websites.
