Non-mandatory reviews can then also come with a "price" to pay: if CI errors are not dealt with in a timely manner, you should be free to disable the CI for administrative reasons...

While this does seem like a nice solution, unfortunately for many
repositories it isn't a case of disabling CI coverage for it, but also
CI coverage for everything that depends on it. In the case of
KContacts, this would also impact on parts of Extragear and Calligra
(who depending on their exact requirements would either lose a
dependency being available, or lose all of their CI coverage).

This is why i've not pursued this as an option in the past, because
it's not fair on other projects that don't have anything to do with
another project aside from being a user of it's interfaces to lose
their coverage, simply because the project they depend on is broken.
