Buffer size has nothing to do with feature richness. Assuming you are asking about DC - in a wide radix low oversubscription network shallow buffers do just fine, some applications (think map reduce/ML model training) have many to one traffic patterns and suffer from incast as the result, deep buffers might be helpful here, DCI/DC-GW is another case where deep buffers could be justified.
