No, it both looks and works better than what we currently have.
The current slit trenches look like a hole dug in the ground and some bushes covering it and they're mostly just used as a cheap tank trap because Osttruppen are better off being in cover than garrisoned, not to mention that they're weak.
These trenches actually could be relevent and see much more use.
I think you misinterpreted my comment we both agree that wider's versions is better.
As for actual discussion on this trench style its much more visually appealing and provides some semblance of movement, is it wide enough for Paks to go in?
