Plus the fact that it's very time concuming *and* error-prone to maintain
these private patches, and then we don't really know what we are testing,
nor is it easy to know when a failure occurs whether it's due to local
changes, or new updates, or the changes being tested.

Really, having Ada broken, and then no fix or revert for days is not
a workable situation in practice.
