Create a GitLab bot
We're likely to need a service to manage some odd operations concerning GitLab. For instance, @allan wants to have MR notifications posted to some mailing list.
I believe adding a small very custom service for this that we continuously expand as we need more stuff is reasonable and probably the least painful way to do this going forward.
The way I imagine it to work is having a daemon that consumes the GitLab API and does stuff.
Gitlab doesn't really have any non-real-user accounts right now but luckily, GitLab is apparently getting service account support very soon: https://gitlab.com/gitlab-org/gitlab/-/issues/6883#proposal
