I did (local definition on top of 13.0.6).  I had also been running, 
since yesterday with:

#+begin_src emacs-lisp
(unless (fboundp 'TeX-reader-sync-view)
 (defalias 'TeX-reader-sync-view 'TeX-xreader-sync-view))
#+end_src

Which is equivalent for all practical purposes.  And, as far as I can 
tell, things are working as expected.  Hence, it LGTM.

The tiniest nitpick.  I usually see the name of the program as 
"Xreader", with a lowercase "r".  But I'm not sure it is even worth the 
amend.  I certainly won't pester you further about it. 

Best,
Gustavo.
