No, there's only one Tramp branch, which is deployed on master and on
GNU ELPA.

Tramp uses an own declare form `tramp-suppress-trace'. In order to make
it happen, there's the code

--8<---------------cut here---------------start------------->8---
(eval-and-compile
  (defalias 'tramp-byte-run--set-suppress-trace
    #'(lambda (f _args val)
	(list 'function-put (list 'quote f)
	      ''tramp-suppress-trace val)))

  (add-to-list
   'defun-declarations-alist
   (list 'tramp-suppress-trace #'tramp-byte-run--set-suppress-trace))))
--8<---------------cut here---------------end--------------->8---

Perhaps this trick could be used?

Best regards, Michael.
