Related to https://bugs.kde.org/show_bug.cgi?id=494679 and after a discussion in the VD group: it would make sense to make templates in the dolphin context menu easier to discover and customize for users. Probably best by linking to the kcm that allows setting an XDG_TEMPLATE_DIR in the context menu. Imho if there are no entries yet, a "Add custom entries ..." entry with a link would make sense, and a "Edit custom entries ..." entry if there are any. It should be in the section of custom template entries, since the other ones are not user-customizable. This feature request would then also require adapting said KCM to make it easier for users to understand what a template directory is, potentially with a GUI method of opening it / adding files, but that shall be a separate feature request.
