However .... usually few bees will stay with a lost queen, and if many do you maybe be able to recover what would otherwise have been a lost swarm. There is also the consideration that swarms take a lot of bees and may end up being destroyed on the orders of the new host if they've gone somewhere inconvenient ... or they may simply die out overwinter (60ft up a Lawsons cypress or otherwise!).
So from the point of view of:
a. keeping most of your bees
b. avoiding upsetting neighbours
... it makes good sense to remove that piece of dry, dead tissue.
