Yes, I agree, the categorization and metadata for items ("stackable", etc...) looks like it was knitted with a very hot needle.

Problem here is probably that fixing this big amount of data (remember: game has tons of distinct items, I'd say its on the order of hundreds) would require a whole team that coordinates what goes where and then do all the changes. Not a very creative and inspiring line of work, people hate this in other fields of software engineering, too (thats why ERP software still looks like it was done back in the 90s, etc...).

"Have some standards" is the right advice here in my most honest opinion - not only us, the players, but also when it comes to approaching itemization details.

A good practice in software engineering for such things is to have a general set of guidelines which are flexible enough (withing boundaries) to allow for addition of new categories (or metadata fields), but still expressively spell out what defines a "category" or a "metadata field" justifies.
