The only issue with modern modding is that they become obsolete with pretty much every update and modders burn out (former modder myself) and we can’t keep up. We move on, but some ppl still use our mods. Update and boom no more mod. I have games that I can’t even imagine playing unmoderated (looking at you Skyrim).
iirc modding the party size is trivial, merely a tweak of a text file (which shows that it is a deliberate choice by Larian).
