Wikipedia:Avoid using meta-templates

Template messages allow certain standard text to be included on many pages, usually with the idea that in the future, any changes to that text block can be changed in one place. The term "meta-templates", as used in this article, refers to nested templates which are created and used to add functions or formatting to other templates.

While they can be extremely useful and convenient, it is proposed that they be avoided due to concerns that may not be immediately obvious: Meta-template schemes can be fragile and hard for new editors to understand. They may also provide an avenue for mass-vandalism and impact maintenance efforts. The reasons listed on this page argue against using meta-templates.
