After fix of bug 26574 I have notice, that the create protection is also not in $wgRestrictionTypes, so it is not possible to disable create protection on a wiki.
This can be more complex, because create protection is listed on Special:ProtectedTitles, not Special:ProtectedPages, the api listed this with list=protectedtitles and not with list=allpages&apprtype=, due to seperated database table.
It is possible to disable create protection?
Thanks.
