I have no issue with BG3 maps.
Sure its not really realistic to have content this dense, but its massively time saving.
Realistic is you make an at least 100 by 100, so overall 10,000 times larger map, and even then its still a stretch that the goblins cant find the druid grove.
This is really a case of realism being counterproductive.
For the record BG1 was a lot more like the OP demands. And it means you have maps which take ages to explore with not much on them. Not good.
