To be fair, what gave the Original Trilogy its authentic, lived in feel is that weaponry, technology, and tactics were modelled after real-world equivalents. The problem with the bombers in TLJ is that they make absolutely no lick of sense even within that context.
Dropping bombs from high altitudes was primarily only effective and used against stationary land targets, because the whole point was to allow the bombers to drop their payload from a safe distance. Sending them up close like in TLJ completely defeats the purpose.
The moment you need higher precision against moving targets, it’s dive bombers and torpedo bombers that shine, and SW already has equivalent to those in the form of Y-Wings and B-Wings.
