Dunno about BG3, but in 5e there are weapons that have farther reach (10ft) than usual (5ft) like whips, halberds, pikes, lances, etc.. but they´re usually heavy, besides whips. Bows and crossbows have larger killing range than javelins, etc.
I assume they will use those rules in bg3 too.
https://roll20.net/compendium/dnd5e/Weapons#contentI think it´s a great idea that you have combat moves that are tied to the weapon you are using, that would give more variety when you are in close combat quarters and you could have more tactical reasons to pick one weapon type over another.
It would be cool if they apply this to the PNP too.
