I didn't say that that churn is a good thing.
The github-issue and a sibling are folks asking this question. Why? Lingering bugs? Waiting for features? That the question is open is the concern.
And again, compared to my existing tooling which is not having that question and has momentum.
Evaluated against docker (a recent move for us) but didn't choose. We also looked a "roll your own" type solutions - required expertise our team didn't have.
