That is an interesting question...
I would guess that it depends on a number of things. What kind of batteries are you using in the trailer? How do you charge/maintain the batteries in your trailer when plugged in, by old style single step converter or by modern multi step style? Do you ever need to use your trailer when not plugged in along the way, for example at a Walmart? The idea of a switch to turn off the charging from the tow vehicle adds another item for your check list or in other words, something to remember and manage.
I like not having to think about it and we do in fact get use of the trailer while not plugged in so we simply suffer the less than perfect charging of the battery while driving...
What I should do is install a regulator between the tow vehicle and the truck...
Loving our 2021 Globetrotter 25 and our 2022 Ford F-150 King Ranch 5.0!!! Plenty of payload, not even close to axel limits and it drives and rows beautifully…

If the batteries in the trailer are charged then the potential seen on the other side of the 30a fuse by the voltage regulator will be no more than slightly high than the wet cell battery in the truck. There's no issue here. However keep in mind that the charging system in the truck is not designed to output continuously for hours on end. It is meant to briefly charge up the start battery and back fill the loads on the system which generally aren't that high.

Recommend considering a Sterling ProCharge Ultra. It is the best charger available.
