$wgMFContentNamespace replicates functionality in core $wgContentNamespaces.
Switching to it, will empower lots of wikis who have correctly configured $wgContentNamespaces but not wgMFContentNamespace to search the correct namespaces and will also improve the nearby feature by searching other available content namespaces.
Plus.. removal of code = profit
