The main reasons are:

    1. My applications have no dynamic "linking"
    2. The containers are distroless
    3. Services can be built independently
    4. I run the same exact sha in dev/staging/prod

To do what you're suggesting would require giving up one of my features which for me is not worth the trade off of a one-time setup 40min build of 20+ services (~2min/service). The last time I paid that 40min cost was ~2 months ago when I reformatted my hard drive.

The better solution for me is looking into a build system that can support my different language and tooling choices which happens to be things like Blaze (Bazel/Pants/Buck/Please).
