If I got to [[ https://commons.m.wikimedia.org/wiki/Special:History/User_talk:Andr%C3%A9_Costa_(WMSE) | Special:History/User_talk:André_Costa_(WMSE) ]] (in mobile view). There is no indication that I'm in the user_talk namespace. While making the distinction between main and user namespace might not be critical (you are unlikely to intend to go to one but end up on the other) not making a distinction between a namespace and it's associated talk namepace is likely to lead to confusion.
Examples which all look identical:
* [[ https://meta.m.wikimedia.org/wiki/Special:History/Talk:Mobile | meta:talk:Mobile ]]
* [[ https://meta.m.wikimedia.org/wiki/Special:History/Mobile | meta:Mobile ]]

= Developer notes
MinervaTemplate currently has no concept of links/components that can be placed above the heading. We'd need to add this capability inside Minerva before dealing with this in MobileFrontend. There is no precedent for doing this and this would only work on Minerva - not other skins.
It would be easier to put the link under the heading e.g. consider breadcrumbs on https://m.mediawiki.org/wiki/Reading/Web/Team
