I posted a few more details on github:

An update to the proposed patch (more apparent error checking, correct
for both LuaJIT/5.1 and 5.3). And hopefully a solution to the
portability issue at hand (at least for some architectures).

Hans, Luigi, what do you think?
as we have a patched lib in luatex ayway it's ok i guess
Of course there is a runtime cost, though negligible and it brings space
savings, which is a trade off the Lua guys have already made in 5.4.
hard to say it it saves something
I also think that the byte swapping for big/little endian could be done.
If the saved format is little endian there should be no cost for most
architectures (unlike the dump sharing on TeX side).
less important i think (and it has a quite a penalty on native windows
binaries but maybe that's because of these allocations not being optimized)
Kind of related:

whatever we do it should be a compile time option (if only to not give
people yet another reason to complain that luatex is so slow)
