Rogues being one of my favourite classes I frankly have no clue whatsoever what purpose they serve in BG3 when anyone can use a lockpick and their perhaps their most defining combat skill has been reduced to...actually I don't even know how sneak attack in BG3 works or what it does. It should be straightforward, why did they needless complicate/ruin it?
In 5e, anyone can take the criminal background for thieves tools proficiency and pick locks.
However, rogues did get shafted by sneak attack's implementation, cunning action's handout, and expertise missing. Hopefully these will be fixed while we are still in EA.
