Also, if you add a new target that would benefit from tracking dependencies between files, then make is already ready to do that.

I use makefiles for my Rust code with just default+test+install targets that do no dependency tracking (since Rust's build system already does that much better). But if I need to add a target for, say, validating some OpenAPI spec that only needs to run if the spec file updates, then that can go in the same Makefile.
