I agree with many of the points expressed, and as someone who has used docker in production I have run into many of these issues myself. At the same time, I value composability and I don't want docker to have a single monolithic approach to everything. Garbage collecting old images, fine, even though its not that hard to deal with the issue. Logging and distribution of secrets don't feel like docker-level concerns to me. There are good solutions for both.
