would you mind putting @jangorecki (and yourself?) as CODEOWNERSnfor GLCI?

[jangorecki]

I think this part is unrelated to the issue that this PR is meant to resolve. Also I think any changes to codeowners shouls be discussed before putting other people into it. I would like to assign myself to ci file but knowing I won't have time for really maintaining it in near future, I would not do so.

I see Michael's comment just now which nicely asks about it. Thanks

@jangorecki I agree, I probably should have asked before putting your name there. But I don't see it so much as a burden that you have to review everything, but more as documentation (other than git blame) and a chance for us to get your thoughts and feedback (when needed) on changes there.
