No, I mean that even for some people unfamiliar with `pcase` syntax, the
`pcase` syntax is simpler (more natural?) than the cl-`case` syntax: the
incorrect use of `quote` in `cl-case` predates the invention of `pcase` :-)

I don't think `case` is objectively simpler.

More specifically, I believe that if you're familiar with neither `cl-case`
nor `pcase` syntax, it's not easier to learn the `case` syntax than the
subset of `pcase` syntax which covers the functionality of `cl-case`.

It may even be objectively easier to learn the `pcase` syntax since it
doesn't suffer from special cases like when you want to distinguish one of
the `nil`, `t`, or `otherwise` values.
