Never really liked how walls attach to water (and cliffs), this mod disables the visual connector from showing for all walls using data-updates.lua.

Normally i just keep a 1 tile gap of air or landfill to prevent it from showing when i try to design something nice, but the space exploration spaceships kinda forced my hand to finally make this mod since i can't stand all the outside facing walls "connecting" to space.

This mod only changes the graphics, it will not allow entities to walk there again as though there was a gap.
(unless wube based that logic on the existence of the water_connection_patch prototype, then it will :o)
