The reason I didn't propose this simpler-to-use idiom, and rather
proposed the GC-root data structure to be allocated by the caller, is
that your simpler construct would likely involve either additional
memory allocations, whose overhead we're trying to avoid, or a more
complex data structure, which also comes with its overheads in terms
of memory and computation.
