There are situations where I've found this would be useful. For instance, in doing room designs, I achieve scaling by setting the grid to one unit per inch. From a zoomed out view, it would be nice to be able to draw a 123 inch long wall, but because the grid point corresponding to "123" wouldn't be displayed, I find myself approximating, then zooming in a few levels and tweaking it to get it right. This isn't a huge deal - it only takes a moment to zoom in, fix the line, and go back, but it's definitely a case where snapping to a non-visible grid point would be useful. If I'm in a hurry I sometimes just use the arrow keys to nudge things closer to where I want.
This is pretty close to what I was doing.
I selected Document Properties > Grid/Guides > Grid units == mm Then under "Grid Snapping" in Document Properties > Snap, I enabled "Snap bounding boxes to grid", "Snap nodes to grid", and "Always snap". None of these gave me any impression that I was enabling snapping only to a visible grid, I believed it was the grid I'd just specified on the "Grid/Guides" tab.
The Snap tab is fairly crowded, but perhaps an "even hidden gridlines" tickbox (disabled by default) would both provide the option and alert the user that grid snapping mightn't blindly work to the specified grid.
In the end I used a mixture of zooming in/out and, when it was hard to place points relative to each other without seeing the context, I disabled snapping, put points in roughly the right place, before (with snap re-enabled) jiggling the points individually to snap them again. I estimate this was, overall, 3 times slower than with snapping to all grid positions.
