I have heard about it, but I used Master Audio 2022 asset for Unity to manage all my sounds in this project.
I got it in a bundle once and is also really cool tool and I think they might also use Scriptable Objects in their code itself. You can also set a lot of values like dB and such (which I should have done better ;-) ) and buses and mixer etc.
But if you have made a nice reusable component that does the job very well that is definitely something to stick with and use. Plus maybe even share or publish it (Asset Store) when more robust and scalable.
Good tools are always welcome for Unity Developers :-)!
