The desire would be to work with sound artists and acoustic designers and product designers and engineers to make certain types of audio spaces. A lot of the cutting edge of acoustic research is from people wanting to make materials and spaces do certain things with sound. For example, this article describes a system that lets sound through one way This was described in https://www.scientificamerican.com/article/a-one-way-street-for-sound/ https://www.scientificamerican.com/article/a-one-way-street-... ("an acoustic circulator") - the need will come from things like this. And for musicians, artists, and instrument makers to make use of materials, devices, and spaces like this. That would be my answer to your question of where the need/why will come from. Imagine needing to write a DAW module to deal with "one way sound" that results from using an acoustic circulator in a musical production or a song.
