Feel free to re-add it.  I was torn about whether to remove it.  Anyway,
most of its code is now integrated into the main 'emacs' package, so it
should be a lot simpler now.  Here's a first draft (untested), but of
course it should be updated to a later commit:

--8<---------------cut here---------------start------------->8---
(define-public emacs-next
  (let ((commit "c36c5a3dedbb2e0349be1b6c3b7567ea7b594f1c")
        (revision "0")
        (emacs-version "27.0.91"))
      (inherit emacs)
      (name "emacs-next")
      (version (git-version emacs-version revision commit))
         (inherit (package-source emacs))
         (method git-fetch)
         (uri (git-reference
               (url "";)
               (commit commit)))
          (base32 "0mlrg2npy1r79laahkgzhxd1qassfcdz8qk1cpw7mqgf6y5x505h"))
         (file-name (git-file-name name version))))
       `(("autoconf" ,autoconf)      ; needed when building from trunk
         ,@(package-native-inputs emacs)))

      ;; TODO: consider changing `emacs' to use a more robust way of
      ;; specifying version for "EMACSLOADPATH", so as to avoid having to
      ;; duplicate native-search-paths here.
       (list (search-path-specification
              (variable "EMACSLOADPATH")
              ;; The versioned entry is for the Emacs' builtin libraries.
               (list "share/emacs/site-lisp"
                     (string-append "share/emacs/" emacs-version "/lisp"))))
              (variable "INFOPATH")
              (files '("share/info"))))))))
