Sure, but the data contains pointers to other data (and perhaps to code?
I haven't checked), and when the pointer-containing data is loaded into
a fresh Emacs those pointers need to be relocated appropriately for the
new Emacs.

Ah, but they can! Because Emacs now assumes the LSB representation,
Emacs objects now encapsulate pointers simply by adding a constant to
them. All C compilers and linkers support that, even for addresses
defined by other compilation units.
