Jacob and I just tested this with a test account that I had around. A new
fork starts out with disabled workflows. But forking before this and then
resyncing / pulling remaining changes, does lead to the workflow being
disabled.

Yes. I spent a decent chunk of time helping folks set up CI for
cirrus-ci. And yet there continued to be folks that were surprised you could
run CI for yourself.

We clearly would need to have an opt-out from that from the get-go, otherwise
I couldn't even test that things are still working before merging, and
postgresql-cfbot won't work... Thomas has it otherwise mostly ready to go
(this thread actually is being tested automatically already).
