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
cea0434c4f7f7f1fc1547e6790b96a76bc217e15
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))
