should this be a game option the user can enable?

I don't think so. SDL_SetRelativeMouseMode is, as far as I can tell, a better implementation of a feature OpenLoco had implemented (hiding the cursor and detecting relative mouse motion, without your mouse movements being limited by the size of your screen/window).
It should be look and feel exactly the same to users, except it will now work properly even in edge cases such as starting the right click drag from a position near the edge of your monitor.
The only reason I left the old system in as a fallback is because the documentation says "If relative mode is not supported, this returns -1", and I was being perhaps overly cautious?
The benefit of this is that the mouse is not able to get stopped by the edges of the monitor when using relative mode, thus slightly improving the user experience. Now right mouse dragging works as expected even you start from the edge of your screen!
