so use Bazel or buck2 if you need an iteration on make's handling of changed files. Bazel is much more serious of a project than buildkit. I'm not saying make is more functional that buildkit (it might be to some), I'm saying its better written software than buildkit. two separate things
Bazel just seems so... Academic. I can't make heads or tails of it.
Compared to a Dockerfile it's just too hard to follow
Oh I love Bazel. The problem is that it’s harder to adopt for teams used to just using make. For a particular project at work, I argued unsuccessfully for switching from plain make to bazel, and it ended up switching to cmake.
