9kHz AM is the standard for shortwave broadcast AM and in
theory gives us compatability with the sets SWLs use.

Broadcast SSB never took off, although it looks like change may
be happening with DRM.

There is an arguament that amateur digital voice should also aim
to retain compatability with SWL's receivers.

The DRM standards allow several bandwidths, not just 9kHz.

SWLs form some part of the membership of amateur radio societies.
They are also a source of future amateur operators.
Building and operating receivers is a perfectly valid form of amateur
radio that doesn't need a licence and is the only choice in countries
where licences are impossible to aquire.
