Request #10460 has been accepted by Alad :
When a maintainer orphans a package, the maintainership is transferred
to any remaining comaintainers.
In this case however, the removal of the comaintainer was done _after_
the package was orphaned by the original maintainer (who added the
comaintainer) and adopted by the orphan requester.
This either means some indisclosed happenings or a hickup in the AUR,
thus the 2 week grace period should be followed as usual.
