Slang provides a standard and open source solution that's better and more featureful than those custom solutions.

For a greenfield project, perhaps that makes it a good choice, but using it to replace established systems needs more arguments than "it's better". Is it really better than a existing, bespoke solution? Keep in mind that the shader language is just one part of targeting a graphics API, you still need a lot of boilerplate surrounding it and Slang doesn't (and probably shouldn't) solve that problem.
