David, I'm disappointed.

Not at all much more convoluted, just different.
I think you should make a 2nd attempt, starting with
things like


with versions

  showMethods(plot, class = "...")
  showMethods(plot, include = TRUE)
  showMethods(plot, class = "...", include = TRUE)

or then directly

  selectMethod(plot, "<class>")


and yes, this is all not relevant to  evd  where the methods are
S3 only...
