Considering builders no longer build roads between cities, they basically build everything within the city limits.
You have to build/buy them, and then they build things instantly.
There's already the mechanism to place things by the city (with districts and wonders).
Maybe they should cut out the middle man and just have improvements built or bought (cheaply) from the city build menu.
There'd be some rebalancing needed (no more out of the city chopping for quick starts, no more building builders in your capital and sending them to new cities to quick start), but they sort of seem like an unnecessary extra layer in the game at this point.
