I didn't look closely into the issue, but I think the main reason is
that Element parses headlines thoroughly, including all properties,
scheduled keywords, which is not, by default, the case for
`org-map-entries'.

For most use-cases, you don't need the parser for headlines, as their
grammar is context free. IOW, `org-element-parse-buffer' doesn't predate
`org-map-entries'.
