Comment (by duog):

 Another note: -split-sections does not apply to shared libraries, and
 passing -dynamic to ghc shows no difference between 8.0.2 and 8.2.1.
 Profiled dynamic libraries do not appear to be packaged, so I have not
 tested the -dynamic -prof case, but I'd expect there to be no difference
 there either.
