It's certainly not impossible that I could be wrong, I haven't tested it myself. I wrote it a little to "this is why" strongly when it's more of a theory.
That would be my concern personally - is the battery draining over time as it sits and waits for a signal. We're always told it will last forever and be insignificant, but often it pans out a lot worse.
My understanding of the context was that it was the batteries for the remote.
FWIW, it's eminently doable to have the light and battery plugged in together and not have it drain the battery. For example, many of the self contained units that include both the light and battery do well for long periods of time. The technology isn't even difficult. My Lupine Wilma of 2013 vintage will operate as you describe. My Lupine Piko a year later is much better. But that isn't even the issue - it's the designers who decided to not implement a lot of the power saving techniques. I have customers who operate similar circuitry which consumes microamps or less while in standby in similar applications.
