Author here. Mill definitely works pretty well for monorepos. Within a single module Mill incrementally compiles the Java files, between modules Mill caches and parallelizes things much more aggressively, and when running tests Mill can take your PR's `git diff` and selectively execute only tests downstream of your changes.

This all comes built-in without any plugins or anything, and serves to help speed up dev and CI workflows even on pretty large codebases.

Does Mill have the capability to enforce dependency constraints on transitive versions without declaring them explicitly? I find this to be quite a useful feature for dealing with automated security review and gradle can do that:

Yes, that's handled by Mill's bill-of-materials (BOM) support https://mill-build.org/mill/fundamentals/library-deps.html#_...
