The greater issue that there is still no way to prevent those types of composability bugs.
Using this approach since 2017 I've never really encountered the types of issues mentioned in Yuri's blog post. The biggest issue I've had is if some user-package makes a change that is effectively breaking but they don't flag it the associated release as breaking. But this isn't really a Julia issue so much as a user-space issue, and can happen in any language when relying on others' libraries.
