I thought lane change tracks would not run properly in analog mode.

Well, they certainly won't operate as lane changers when there is no digital signal to control them, but they work just fine, depending on the specific lane changer type. Double lane changers are no problem at all. Some single lane changers, such as the curved ones, have wiring that bridges the two lanes, and so require a simple wiring modification.
Yes, I am referring to Carrera Digital, and not Scalextric.
But, that's probably one reason they have not, and likely will not, add an analog mode.

Scalextric decided to phase out the curved lane changers entirely.

either way, if you removed the lane changers that had that wiring issue, there's no requirement to put analog X tracks in place of them.
