I just had a look through some of the recent issues with the accepting merge request label and most of them refer to enterprise edition issues but only a small number have the label "enterprise edition". Many of them have other tags like "Category:Epics" but there seem to be a very large number of these EE edition labels making it not simple to just filter out enterprise edition features.
Thanks for pointing that out. I've also seen missing "enterprise edition" labels in some MRs and can make a request to GitLab team members not to forget about the enterprise label.
