Well, I know that they are different things. But does the change in spring
rate on its own not provide a retarding / impeding effect on the compression,
just like an oil orifice does for a constant wound spring? The higher the
force on the spring (speed of approaching / departing terrain), the higher
the resistance of the spring or oil density. Right? I mean the oil determines
with what speed the compression changes, but a change in spring rate also
changes that speed in a similar fasion... doesn't it?
A similar thing I read here about multi-leaf springs, which also progressively
change spring rate with compression:

"The multi-leaf spring has a rudimentary ability to increase damping with load,
due to an increase in inter-leaf friction."
