I learned how to drive in a 1952 F3 pickup on the farm. It had the old 4-speed non synchro gearbox so it was a learning experience downshifting all the way through the gears. The double clutch is a way to slow the countershaft cluster gear so that the shift will be manageable. The RPM matching is the most important part about downshifting but the two actions work hand in hand. Each different transmission of this type is a new experience but just having the knowledge of how to best negotiate a downshift is a big plus in the process.

I had to drive an old late 40s International fire truck when I worked at an airport up in Kansas. I was the only one that could drive it without grinding gears. Anyone that has experience with the old Internationals will know what I'm talking about. It had the weirdest shift pattern of any truck I ever drove.
