The only instances in which should be used are those in which the name of the page is conjecture or will never be disambiguated.

Consider the instances in which you keep using it - mission articles. Who's to say we're not going to get a mission called "Blockade" in Ace Combat 7? If that happens, we'll need to move the current Blockade article to "Blockade (AC04)" and make a new "Blockade (AC7)". But if we have PAGENAME on the current 04 article, then the page will display "Blockade (AC04) is the fourth mission" etc. and we need to remove PAGENAME at that point.

tl;dr Try not to use it.
