Is it possible to disable paths?

[SymKensaki]

I find that paths are typically ugly, overlap strangely, and more or less completely rule out the ability to use "layout_position=LAYOUT_POSITION.CENTER" without putting every single thing you use it on, on a path.  I know they play some role in the connection of maps, so I would be perfectly happy with making them invisible and disabling their speed boost, but I just can't seem to find anything regarding their placement or how to affect it.  Roads are easy enough to disable, but paths elude me.

 

Anyone have any insight into how I might do this?
