That statement is incorrect.
Even then "Debian" actually means "an OS installation", iwd is a part of
the main archive, iwd can be installed by user, and iwd can be used to
configure IEEE 802.11-compliant network interface.
Whenever the file mentioned should be used by iwd in any way is a
different question, of course.

Not entirely correct.
interfaces(5) is only used by either ifupdown or ifupdown2. While the
former has "important" priority (the latter is "optional") in bullseye,
it's still possible to run Debian, but have no ifupdown or ifupdown2
installed.
And even the "correct configuration" of IEEE 802.11-compliant interface
at interfaces(5) will do no good unless wpasupplicant (which has
"optional" priority) is installed.

Pretty accurate description, barring the fact that NetworkManager by
itself cannot actually configure 802.11-compliant device. It uses
wpasupplicant (which iwd is an alternative for) to do that.

Such a harsh description of a poor systemd-networkd.
And calling a simple set of plain-text configuration files "crazy" is
way too close to exaggeration. "No popular Linux distribution is using
systemd-networkd by default" is much closer to the truth.
