There's a second question of relevance here: would this change help
solving similar bugs in other modes?  Consider for instance an Org file
like this


    (

    #+begin_src
      f(<type close parens here>)
    #+end_src

or a Markdown file like this

    (

    ```
      f(<type close parens here>)
    ```

Of course each of these modes could define their own
electric-pair-skip-self, but ideally a general mechanism to deal with
this situation should we provided.

So I guess my question here is: does it make sense for a major mode with
a notion of "code blocks" set field properties as part of the
font-locking?  Or is there any reason not to mix up fields with
font-locking?
