I see it as more work now for all the feature you actually need, and less
work later.

 There's inherent value in having as few platform specific bits as
possible.  When the same rules apply to every platform,
a) everyone gets better test coverage
b) everyone gets to benefit from everyone else's changes and bugfixes
c) as a user, it makes it easier and more comfortable to switch platforms
since you don't have to do a mental switch.
d) It makes the code easier to maintain
