Yeah, definitely. The compiler has a few features recognising this already, e.g. there's various levels of optimisation (0 through 3) and, more significantly, there's parallel codegen where the compiler will internally divide up a single crate into multiple compilation units and optimise/run code-generation on them in parallel (this reduces how much each compilation unit sees and so reduces optimisations like inlining etc.).
