Erratum 7832 in RFC 9539 is correct and should be marked as Verified.  The
"damping" parameter should indeed be characterized by the specific
encrypted transport it is associated with.

A recursive resolver that implements both DoT and DoQ may perfer to use
different `damping` parameters for each encrypted transport, for
example due to concerns about different resource consumption patterns
for each implementation.

Thank you Kevin P. Fleming for the close read of this document.
