I feel your pain; I'd like to have the simpler interface, too.  The
problem I see is that it is not possible for an implementer to choose a
single best implementation for all users of the platform.  Some users
will want constant folding and some will want binary (i.e. hand-crafted)
precision.  It's not a matter of one implementation being higher quality
than the other; it's just a matter of having different tools available
for different jobs.
