No, you're missing the use case here I think. It's all about releasing
minor upgrades (of extensions) and allowing users to jump through more
than one of them at a time. Like upgrading from 1.1.0 to 1.3.5.

If you have extension which needs multiple major version releases, then
yes, as PostgreSQL packages, you need to put the extension major version
number into its name. I don't see that as a problem of the mechanisms
proposed here.
