There was a problem hiding this comment.
This heuristic is no longer working as intended with non-ssg pages and it was there to support really old gatsby version (early v2?)

Description
This fixes essentially running
getServerDatatwice for same page (once for html and once for page-data) by inlining page-data in html response and hydrating pageData cache so that we never even need page-data requestNote
This will require also Link headers to be not be there for
page-datafile whengetServerDatais used
