Surely the .eln files won't be in the same directory as the .el and .elc files, at least not on GNU/Linux platforms. On a Debian-style system, .el and .elc will be in /usr/share/emacs/28.1/lisp/foo.elc (or foo.el.gz) whereas .eln will be in /usr/lib/emacs/28.1/x86_64-linux-gnu/lisp/foo.eln because it's machine-dependent and can't be shared across architectures. This will require more load on the filesystem due to the extra directory lookups. Also, how should site-lisp work? Currently on Debian it's under /usr/share/emacs because it's architecture independent. Will we need two site-lisp directories too? Similarly for users' .emacs.d directories -- will they need a more complicated structure, for users who run different versions of Emacs or Emacs on different architectures with shared home directories?
