Comment 5 for bug 1652269

We are - as always - trying to clean and recheck old bugs.
This - sadly - clearly is one of them.
The situation is still correct, but with the full switch to networkd and netplan as well as the demotion of ifupdown in later versions of Ubuntu this has become even less important. And it didn#t even find enough importance/attendence before :-/

I'm retagging this as a Xenial/Bionic issue, because later releases would just work totally different anyway.
