You are of course right. There are other page attributes that can be
inherited, btw (see table 30 in the PDF norm).

"(Required; inheritable) A dictionary containing any resources
required by the page (see 7.8.3, "Resource Dictionaries"). If the
page requires no resources, the value of this entry shall be an
empty dictionary. Omitting the entry entirely indicates that the
resources shall be inherited from an ancestor node in the page tree."

No merging is to be done, just a replacement. Merging would be
interesting, but probably too difficult to implement.
