It is not a "trick" but is a basic courtesy for reviewers. Even if you do
not have any $ to worry about, _unless_ you actively know you would want
variable substitution to happen, it is easier for readers if you signal
the fact that the here-doc is verbatim by quoting the \EOF marker upfront.
Same thing for use of single quotes vs double quotes when writing strings,
even though they tend to be small and much less of an issue.
