Kaban's hat and pith_helmet -> helmet implication

Can we talk about this again? Last year, I moved a bunch of posts from safari_hat to bucket_hat, I'm pretty sure all of those posts later got moved to pith_helmet which implies helmet, and Kaban's whatever thing that she wears does not look like a dang helmet.

It appears it was Zettamorose who bulk-moved several thousands Kaban posts a couple months ago (link) from bucket hat to pith helmet.

Wikipedia lists it as a type of helmet, since it has a reinforced top. Keep in mind that a helmet is not a helm. Looking at the most popular posts for kaban's tag it seems like the hat is indeed drawn by most artists as a rigid protective helmet.
