[Mediawiki-api] There is no API call that will just return a list of page names with no added junk

There is no API call that will just return a list of page names DebConf18/DayTrip/Registration/A DebConf18/DayTrip/Registration/B DebConf18/DayTrip/Registration/C like one sees in https://wiki.debconf.org/wiki/Special:PrefixIndex/DebConf18/DayTrip/Registr… without insisting on adding pageid="7823" ns="0" to the result even if one uses prop=info & ininfo=... nor just printing it in the above plain text format without any other junk added, even if one uses format=txt. The best one can do is wget -O z "https://wiki.debconf.org/api.php?action=query&generator=allpages&gapprefix=DebConf18/DayTrip/Registration&gaplimit=22&format=txt" perl -wnle 'print for m!DebConf18/DayTrip/Registration.+!g;' z DebConf18/DayTrip/Registration/A DebConf18/DayTrip/Registration/B DebConf18/DayTrip/Registration/C
