It's annoying in that delve it's not allowed to mount, it's not like an undercroft or crypt with rooms or something, it's open ambient. Doing the quest with multiple characters a day it's just a nuisance not being able to ride.
I have Stamina maxed out on my low level characters horses too for this very reason, to skip trash mobs when mounting is possible and that place is open, feels like mounting should be allowed.
