While I'd favour the naval factory skirt size changes to resolve this over other options such as changing ship sizes, if people value needing cliff-building to the same extent as now so much that it means a frustrating bug for new players won't be fixed, then I'd presume a possible alternative option in addition to this could be to increase the build radius of engineers slightly. E.g. increase by 1 for T1 engi, 2 for T2, and 3 for T3, which I'd expect would give scope for increasing the skirt size slightly without preventing cliff-building in many cases. Obviously there would be wider balance implications of such a change though.
From my recollection of the first time I ran into the issue when playing FAF it made it a really frustrating negative experience, and the main reason it's not been a bigger issue for me is because I've assumed it was similar to the 'Engi bumping' pathfinding problems where it's not possible to fix the issue and so something I'd just have to live with if I play FAF.
