Yes, that would be one (small) advantage. It would also be
easier to provide a portable version. The disadvantage is
the need to use smart pointers at all.
It is not that hard to write a new(gc) and gc_allocator
using Boehm's collector, for those who don't want to have
the collector take over all memory allocation.
