Well, that's the thing? You say it's simple to fix a 'severe' issue... I say it's a non-issue. It takes like a second to rearrange your entire bar, and it's not any kind of big deal that the potion of flamesplosions and acid or whatever I just picked up got added to my hotbar, because it's at the very end. A mod exists because it clearly wasn't a huge deal enough for Larian to mess with it, but a player with know-how made it because they thought it was.

Nothing more or less thant hat. It's only an issue for some people.
