Nah go for it. Sounds like it would give a similar feeling to typing out an argument or a rant and then deleting it instead of sending it. Lets that anger out against the thing without actually screaming it to the world.

Plus, if you bought the dragon from someone, it's not like they'll know why you named and exalted it. I'm sure we've all seen plenty of strange names on our offspring lists. If it's your own bred fodder, then it's just a fun thing to do! Ngl naming a dragon CreakyShoulder and then exalting it, and later telling my friends that I exalted my CreakyShoulder sounds hilarious.
