It has slightly more licensing complications - GMP is LGPL, which
requires that the user of a program that includes it be able to replace
GMP. Shared libraries do that easily. Static linking would probably
require someone who compiles+distributes a program that uses both
Haskell and GMP/MPFR to distribute their .o files (or alternatively
their source code), so that they can be re-linked to a different GMP.
(Their program still does *not* have to be LGPLed.)
The parties I've heard publicly concerned about duplicate packages are
Linux/BSD distros that primarily support Free Software. So that
complication might not even be a problem (provided the GHC user would
get a choice whether to staticly link, and probably default to dynamic
linking).
