The other question (of wider scope) was that on the save format
currently used: Using bits 28-31 of the PFNs to encode their types
(effectively wasting bits 32-63 on 64-bit) isn't forward compatible,
and hence sooner or later will require a change. But of course there
are other tools limitations (restricting guests to even smaller amounts
of memory), but those are mostly internal to the tools (i.e. fixing
them would not break compatibility).
