Could always use a ruler!
Ummmmm, I use a CRT Screen and it is curved...
Ah, but what if there is a grid in a forest and no-one is around to see it!

Non Euclidean Geometry is your friend!
Just because you can't see the grid doesn't mean nodes can't - they operate in a different dimension so still click to align to the grid even when it's dark.
But several inbound PRs should throw some more light on the subject.
Ah, a "quantum grid" clearly. ![]()
The Deploy button, when there is nothing to deploy, is thoroughly greyed out but the "Restart Flows" action is actually still available.

If you click the invisible down arrow to expand the options, I would expect the unavailable Deploy options to be greyed out here, but they are not.
Restart Flows is a valid action whether the flow has been modified or not.
The other three do not actually deploy, they specify which type of deploy to do when the deploy button is enabled and clicked. So it is valid to select one of those whether the deploy button itself is enabled or not.
