For example Special:FeedItem delivers wiki content so there should be a way for special pages to say "my output language is based on wiki content language instead of user language".
Assuming that buttons, headings, tabs and introtext will still be translatable into user language and adapt to the user you shouldn't change the page language but wrap any wikcontent-language content in the right css classes instead (<div class="mw-content-{ltr,rtl}" lang={..}>).

This does not only affect appearance but also behavior of the language converter: if my user language is en I cannot convert contents in Special:FeedItem from zh-hans to zh-hant. Wrapping page in <div> won't help.
