As the tags for debark are ship provided, I'll guess they don't fit well in the holders anyway.
My practice has been to tag the bags at my hotel so they are ready to go out of the cab.
For our last sailing, pre-covid, we drove to the pier, so we tagged at home.
I've also been tagging my carry on (aside from a standard ID tag) just in case it should go astray between boarding and cabin availability.
