I quote that section entirely: """The BDFL said it best: The $ means
"substitution" in so many languages besides Perl that I wonder where
you've been. [...] We're copying this from the shell."""

That states that the $-substitution is common in other languages, and
was copied from the shell. It does not provide a case for the merits
of $ substitution (as opposed to using other delimiters), nor a
rationale why copying from another language is a good idea in this
instance.
