That's right.
Nowadays, *all* files with a `.el` extension should have
`-*- lexical-binding:t -*-` somewhere on their first line.

Emacs-28 gives an orange `/d` warning in the modeline when that line
is missing (and uses a discrete `/l` instead when the line is present).
And you can click on the `/d` to fix the problem.
