Well. if it's a "feature" it's one that requires a bit "salt" along with it. It's fine to be able to set limits to the Bode plot to 1Hz at the low frequency end, but a bit meaningless up in the MHz range. The resolution of the display is less than 1 part in 500, let alone 3.5 more orders of magnitude.
To each their own I guess. For me it looks messy. If it said 2.0M I would be fine with it. I could always go over to the config menu to see if I had actually set it to 2,000,173 - for all the difference that would make in any results I'd see.
