Potentially there is a optimization for caching dynamic link binaries, the time to link is generally 1-5 seconds and the time to transfer from cache is about a 1-2 seconds. The downside to consider is that almost any code change will induce many dynamic link bins to be recached, due to the nature of the dynamic link bins begin far down the dependency tree.

In SERVER-74278 we disabled all linked binary caching because static bins were inadvertently making there way into the cache. If we want to re-enable this we need to verify that static bins do not cached in a nolinked cache build.
