Expose footsteps sounds

[Zughy]

Problem

I'm working on an audio library mod that features accessibility options. In order to display a text saying "Footsteps" that appears whilst footsteps are heard, I need a way to track them. Footsteps, as stated also here #14326 (comment), do not use minetest.sound_play, contrary to e.g. digging sounds. There's no way for me to know when such a sound is played

Solutions

Expose it somehow (?)

Alternatives

Implement audio accessibility options engine-side so I don't have to (#10666)

Additional context

Footstep callbacks would also be useful for many other things, such as changing the node when a player walks on it, showing custom particles as a graphic effect, or for a teleporting node.

btw: footsteps are client-side so this another of those requests that isn't as easy as it sounds (did someone say CSM?).

Implement audio accessibility options engine-side

This is also a good idea.

This is also a good idea

Not according to the discussion in the issue linked in "Alternatives". I've made my mod also because that issue wasn't going anywhere: hearing that now might be a good idea is... tiring. Wouldn't be easier to espose footsteps rather than designing an accessibility API where just the idea of creating something generic enough yet effective gives me a headache?
