The packaging is generally a side-effect of isolation in my experience. I never chrooted a software because I needed a different library stack for it to run, but to isolate it from rest of the system in one way or another (for security/access reasons).

Docker just made the interface more practical, and built the ecosystem around it. lxcontainers, apptainer and podman has improved upon the idea in different ways to cater different use cases.

So for me containers were never simplified ships to begin with. This different perspectives happen probably because people look from different perspectives at initial contact, which is normal.
