There are some files in Emacs master branch that are also distributed
in GNU ELPA for older Emacs, e.g., python.el (I don't know if it has
any pcase instances that you might want to replace, it's just the
first example that came to mind).

Another thing to watch out for is that pcase is available earlier than
cl-case in the bootstrap sequence.
