I've defined an initial list of stakeholders, expanding on what @LarsWirzenius had defined in User:LarsWirzenius/NewCI.
Topic on Talk:Draft:Wikimedia Release Engineering Team/Seakeeper proposal (FY2019-20Q4 rework)
Do the stakeholder descriptions seem accurate to corresponding teams? @JBranaa (WMF) for QTE, @Mark Bergsma (WMF) for SRE, @TCipriani (WMF) for RelEng, @CPettet (WMF) for Security.
Seems reasonable to me.
+1 I think you've covered all the stakeholders I can think of.
