You have nothing to apologize about, I understood you completely.

The latest code should produce an absolute file name in
user-emacs-directory, which I believe fixes the problem you described.  My
response just explained how will Emacs produce an absolute file name from a
relative one when it processes the --init-directory= option.

The fix is in the emacs-29 branch, soon to be merged to master, so you can
try the fix if you want.
