My guess is rather than the profile records (or replays) transformations
in the wrong order:

--8<---------------cut here---------------start------------->8---
$ guix shell kakoune --with-git-url=kakoune=https://github.com/mawww/kakoune.git --with-branch=kakoune=breaking-cleanups --export-manifest
;; What follows is a "manifest" equivalent to the command line you gave.
;; You can store it in a file that you may then pass to any 'guix' command
;; that accepts a '--manifest' (or '-m') option.

(use-modules (guix transformations))

(define transform1
  (options->transformation
    '((with-git-url
        .
        "kakoune=https://github.com/mawww/kakoune.git")
      (with-branch . "kakoune=breaking-cleanups"))))

(packages->manifest
  (list (transform1 (specification->package "kakoune"))))
$ guix shell kakoune --with-git-url=kakoune=https://github.com/mawww/kakoune.git --with-branch=kakoune=breaking-cleanups --export-manifest > /tmp/m.scm
$ guix build -m /tmp/m.scm -v1
guix build: error: the source of kakoune <at> 2021.08.28 is not a Git reference
--8<---------------cut here---------------end--------------->8---

If you change the order of both options in the alist passed to
‘options->transformations’, it’s all good.

Now we need to find the place where things are being reversed…
