issues when setting live.remote's id dynamically

In order to stop generating "undos" for some actions, I had the idea to dynamically change the object pointed by one single live.remote~.
This could be nice especially in the case of a control surface controlling stuff without creating undos, when you don't necessarily know in advance the number of tracks/devices you want to control.

Attached is an example of one live.remote~ "grabbing" the volume of two tracks, using javascript to set the id.

First question : would you say that it's stable/efficient with a larger number of targets ? (basically, is it a good idea ?)

Secondly : I don't really get what's happening with the undo history. It seems that changing the id create an undo entry. And performing undo will then effectively change the tracks' volumes. How is it so ?

Thanks !
