There are templates that have a different name, but the same parameters. For example, the many lang-XX templates. If I see that the parameter text is correct, but an incorrect template was used, and the template should be {{lang-ru}} and not {{lang-be}}, I can simply change the template name. In VE I need to delete the whole template and re-add it. This is silly, but tolerable, for a template with one parameter, but there are such templates with more parameters.
Ideally if the templates are identical but for one piece of information ('be' vs. 'ru') then the template should be used directly ({lang|ru|…}} vs {{lang-ru|…}}, not via accessor methods, which would make this moot. But yes.
