More accurately (and as acknowledged in that guide), a single underscore
*is* a common name for a “don't care” name, but is better avoided for
that purpose because it's also commonly used for other purposes.

In other words: That guide is correct in its admonition, but that
doesn't challenge what Steven said about common usage.
