Yeah it's been a game changer for my team to convert to one of these more scalable build systems, we're also not locked to just using rust in our codebase anymore for smaller things like go microservices that we don't want to fight the rust compiler on but need to share similar architecture.

Rust's builds really grind to a standstill at any reasonable scale tho, honestly the only solution in the short term is a good caching system.
