    Sharing code that should be shared is a good way to improve Emacs
    for the end user because it ensures that when something gets
    fixed it gets fixed at all the places where it's used.

    See src/w32*.c for examples,

That example supports my point.  It is desirable to share code between
w32*.c and x*.c because that is a lot of code to share; therefore, a
large benefit.  Meanwhile, the code already consists of subroutines,
so the other code which calls this code to be shared won't need to
change at all; therefore, one cost is small.

The other cost is the complexity of conditionals added to the merged
code.  I don't know what that will be, but I suspect it will be much
smaller than the benefit.
