Make super forced build insert gates when rails cross walls

Using super force build to build straight rails could insert gates when it crosses a wall, but instead it creates gaps in the wall:

I like this idea...

But what should it do if you don't have gates in your inventory?

Build ghost gates anyway, or build walls?

I figure it would place ghost gates. (Where would it build walls?) This is like if you don’t have underground belts and it places ghost undergrounds. I don’t think force build ever cares what is in your inventory, but I could be wrong.
