Unfortunately, that wouldn't be a complete solution to hairline gaps - for example, in game, they're sometimes illuminated by the room next door.
I imagine the reason why even the night sky looks blue in the level editor is to make the gaps easier to see and fix.
Depending on the tileset, you may be able to prevent gaps by setting XYZ (e.g. fca), or by using pillars between every tile (e.g. fdi).
Either way, snap-to-grid only gives you a starting point.
