This is overhead for every update of every library. In theory it's a great idea and expensive idea, so of course nobody does it.
There are two mindsets in coding, this code needs to work right now and this code needs to work in 20 years. Linking code is very likely to break in the second time frame. Public API's are generally unstable, services goes away, and people break things. But, if all you need is a toy demo then feel free.
