Damn, yeah it makes sense now :)

For multi-arch builds I think special care will need to be taken
anyway. The emacsformacosx.com builds for example have duplicate
shared libraries for each supported architecture. Personally though
I'm planning to just create separate builds/dmgs for each when I'm
able to support anything other than x86_64. The main self-contained
Emacs.app my builds are producing at the moment are already 500MB
thanks to full native AoT and essentially copying most of GCC into the
bundle for libgccjit to work.

Also, I'd obviously be more than happy to help with testing any
further changes to eln file locations and related things :)
