Absolutely. It's certainly something that needs to be a dialogue, not at all "I know something you don't, here is why you are messing up."

There are always circumstances that affect decisions that you may not know of. This is one of the reasons I am always encouraging artists/developers to be knowledgeable of their project at a higher level. The more you know about what's going on in the big picture, the more of an asset you can make yourself. It's also important for sanity! The OP sounds like they are stewing daily about disagreeing with the feature -- but if there is in fact a relevant reason, some of that burnout-causing heartache could have been avoided.

Dialogue and accountability two huge keys to the management/artist relationship.
