Entirely correct.
Technically, this is not required by the quest as such, but to allow you to attack the creature. I'll see if we can add "Required to attack" on the items and "Item required to attack" to creatures. This would then help with things like the Holy Pinata Bat and the Spook Smasher weapons and various others.

Yes, there are a few quests where I have found I needed "x" equipped, only to discover in my research that the item in question was a quest reward or something invented during a previous quest. Although these quests do provide a welcome challenge, it's frustrating to say the least to find out I can't equip this thing or that simply because I either haven't done said prerequisite quest, or I crushed said item cuz I didn't know I needed it later on. Kudos to you and Hoof for showing up on days off to replace these things btw...
