But sometimes humans are not wrong. For example, no released TaskFlow version really works with SQLAlchemy >= 0.8 -- that was fixed only recently (https://review.openstack.org/#/c/62661/). I consider requirements to be part of the code, so if they are too strict (or too broad), that must be fixed, in a usual opensource way: via filing bug report, suggesting patch and so on. Requirements should reflect reality, especially for libraries that are intended to be useful outside of OpenStack, too. For example, current TaskFlow requirement for SQLAlchemy is too strict, so we'll fix that, and release new version with that fix. -- WBR, Ivan A.
