The 'subpage' option in parserTests is supposed to turn on subpage support.
(which is a wiki config thing?)
But parsoid always enables subpage support; that is, /foo will always
link to [[Parent/foo]], not an article titled '/foo'.
We should make that a wiki config option, fetch it via the API, and only resolve subpages if it is turned on. [We could also make the 'subpage' option in parserTests work properly then.]

It seems that the API does not expose this configuration option yet in the 'general' section, so we'll have to add it in MediaWiki core. The Parsoid side of the implementation should be fairly straightforward once the configuration information is in env.conf.wiki. See comment in the patch linked above.
The PHP implementation of the 'general' section is in includes/api/ApiQuerySiteinfo.php. The config variable to expose is http://www.mediawiki.org/wiki/Manual:$wgNamespacesWithSubpages#Enabling_for_a_namespace. Subpages can be enabled or disabled per namespace, so an array of numeric namespace ids for which subpages are enabled probably makes most sense for the API. There are some other arrays in ApiQuerySiteinfo (see appendFileExtensions for example) that can be used as a template.
Example general section for the English Wikipedia (hit 'Make request' and scroll down to see the JSON):

Namespaces with subpages enabled already appear in the API, for example:
https://en.wikipedia.org//w/api.php?action=query&meta=siteinfo&format=jsonfm&siprop=namespaces

The patch landed, but I think support for the 'subpage' option in parserTests did not, as no additional tests pass with gerrit #59929.
See the section flagged with "### Subpages" in tests/parserTests.txt.
