It was compiled with emacs-minimal=emacs.  For reference, I have inlined
the manifest file that was used (with the --no-grafts CLI option to
guix-package) towards the end of this email.  I'm sharing the one that
was actually used, but it could be minimized.

I believe there are two issues (not including the spurious entry in
native-comp-eln-load-path which may already have been resolved in v7 of
the series).  All my observations below are based on v6 patch series.

For emacs-htmlize, I believe the issue may stem from the fact that some
.eln files are available from entries in native-comp-eln-load-path only
via symlinks and the .eln loader may not be able to load symlinks.
Packages such as ox-html are available from two locations in the
native-comp-eln-load-path.  In one location they are symlinked, but
(presumably because org is a builtin package) it is also available from
another location in the native-comp-eln-load-path and in the latter
location it's not symlinked in.  I believe this difference is why for
some packages natively-compiled versions are loaded (e.g. org, ox-html
etc) whereas for others it's not the case.

In addition, I believe there's another issue.  Some packages' names are
getting  truncated.  For instance, instead of uniquify.eln, I observe
niquify.eln.  In this case, the .eln isn't symlinked (presumably because
it's a builtin), but due to the name being messed up (perhaps too
aggressive a truncation of hashes?) the natively compiled version is not
available:

> uniquify-item-p is a byte-compiled Lisp function in `uniquify.el'.

The manifest file that was used is below.

#+begin_src scheme
  (use-modules (guix transformations)
               (gnu packages))

  (define transform1
    (options->transformation
     '((with-input . "emacs-minimal=emacs")
       (without-tests . "emacs-clojure-mode"))))

  (packages->manifest
    (list (transform1 (specification->package "bash"))
          (transform1 (specification->package "coreutils"))
          (transform1 (specification->package "git"))
          (transform1 (specification->package "make"))
          (transform1 (specification->package "emacs"))
          (transform1 (specification->package "emacs-org"))
          (transform1
            (specification->package "emacs-org-contrib"))
          (transform1
            (specification->package "emacs-citeproc-el"))
          (transform1
            (specification->package "emacs-engrave-faces"))
          (transform1
            (specification->package "emacs-haskell-mode"))
          (transform1
            (specification->package "emacs-htmlize"))
          (transform1
            (specification->package "emacs-markdown-mode"))
          (transform1
            (specification->package
              "emacs-org-pandoc-import"))
          (transform1 (specification->package "pandoc"))
          ))
#+end_src

Thank you for your continued work on this!
