Appetite? No. However, it's something we can support (please read on).

While I understand what you are trying to explain I don't see how it
matches what is effectively found in junit jar files. For example,
both junit:junit:4.7 and 4.10 contain classes from the org.hamcrest
package. What am I missing?

Yes, it would be cheeky bordering on rude. I am for publishing
junit:junit:99-empty but only if the Junit folks *officially* sanction

In any case, I very much appreciate the proposal.

Best regards,
