KDK, Yes, you do need to be careful running the metal gauge tip along the rails and not repeat the process too many times. But the same is true with feeler gauges. The edges of feeler gauges is quite sharp so can damage the rails as well.
I've seen one refacer on YouTube recommend taking that edge off, ever so lightly. However, the very edge is no longer the full thickness of the gauge, but only by a very small amount I suppose. The lack of a clear edge on the feeler will also affect how the feeler gauge sits in between the rails and the glass gauge and affect the reading you get. Of course, depending on whether you have the feeler gauge flat again the glass or against the rails, you should get a different reading (if anyone could actually detect that difference using a traditional glass scale).
Rather ironically , there's a point where any measurements are good enough for the relevant purpose. As with mouthpiece measurements, where that point is is a matter of preference, ability, tools, experience etc
