I guess the reason it is not looked at is because it is not used by default, and only one person until now have voiced it as an issue. And he only mentioned that his code editor is complaining about it, not that it causes any actually issues when using ezp.
So please add your findings in the issue and link back to this thread so we can prioritize it higher.
I can not re create this issue actually on 4.1.0.
1. the node locations are not shown / used in frontend (tested in webin) 2. there are no warning at all, not even in the admin interface.
So guess you either use something else then webin, or you have extended it?
