I'm afraid GitLab CI wouldn't have prevented this from occurring - because
the pre-merge CI still needs to run somewhere.
The problem here is that the simple act of running the build
degrades/breaks the builders for everyone else.

In terms of a timeline on this, once I have the situation with Nextcloud
sorted out (which had to be prioritised as the version we're on goes out of
support in the next few months) we'll hopefully be able to work on GitLab
CI (assuming another vendor of ours doesn't go and pull another major
dependency bump stunt like Nextcloud did)
