> As for Python package management, my team is migrating to Bazel which has its own way of locking in the Python dependencies and then pulling them from a remote cache. Under Bazel, we are only re-examining the dependencies when someone proposes a change to produce the lock. It's so rare, that having a new+faster thing that does this part would not present a meaningful benefit.

Have you considered Pants[0], Buck[1] or Waf[2]? What ultimately made you decide to go for Bazel?
