But it can really help understand the practicalities of it, like any paper involving models, which are pretty numerous outside of pure mathematics. Unfortunately, I've seen many papers that "leave it to the reader" when it comes to equations used, with no translation between variable names and what they actually represents.
I feel like that's an issue of the paper, and not the idea; instead of making the math verbose, the paper should provide a legend or key that documents each symbol, or at least the main ones.
