AFAICT, the "cognitive load" of a complex pattern language is about the
same for `pcase` as for `match*` since the two pattern languages are
very similar.

And in the case of code that can use `case/ecase`, `cond*` doesn't seem
to provide much benefit over just `cond` or `pcase`.  Compare:

    (pcase actm
     ('armg (do-this))
     ('go (do-that))))

vs

    (case actm
     (armg (do-this))
     (go (do-that))))

vs

    (cond
     ((eq actm 'armg (do-this)))
     ((eq actm 'go (do-that))))

vs

    (cond*
     ((eq actm 'armg) (do-this))
     ((eq actm 'go) (do-that)))

or

    (cond*
     ((match* `armg actm) (do-this)))
     ((match* `go actm) (do-that))))
