standard/cologneblue/chick/skin/nostalgia skins do not have "permalink" - link to the current revision of the page (it it's an article) and do not support "SkinTemplateBuildNavUrlsNav_urlsAfterPermalink" hook that allows adding more links my extensions (most notably Cite and Collection extensions)
This is fixed for CologneBlue in this commit: https://gerrit.wikimedia.org/r/#/c/25415/
The remaining legacy skins were removed in Ia6d73c2d. Marking this WONTFIX.
This is invalid now that the legacy skins have been removed (Ia6d73c2d).
