I'm also not fully convinced that code generation is an improvement.

Sure, but that's easier said than done.
BTW, the MPS documentation says that mps_reserve allocates a block. In
MPS, a block is not necessarily a single object. One possible
interpretation of this could be that mps_reserve can be used to allocate
a block that contains many objects. Perhaps we could use a single block
for the entire dump? E.g. implement a version of dump_mmap_contiguous
that uses mps_reserve. What's your interpretation?
