That comment was in the context of back-end specific filters and aimed at
back-end developers. You are adding to 
org-export-filter-plain-text-functions, which is for users. So, go ahead
and test.

The changes introduced in commit

  ox: Change back-ends internal representation to structures

necessitate extracting the name of the back-end from a vector.

So, this bit of code 

     (memq backend '(beamer latex)) 

will never return t, because backend is a vector.

Probably what you want is 

     (memq (org-export-backend-name backend) '(latex beamer))
